[Kernel-packages] [Bug 1451277] Re: Extremely high IOWait and processes hungs after utopic->vivid upgrade with Iomega Zip drive (IDE)

[Sergio Callegari]

>From LKML conversation, fix https://lkml.org/lkml/2014/11/20/581 is not
likely to be applied upstream, because it probably just papers over the
real bug.

The real issue appears with the patch series "scsi: convert host_busy to
atomic_t" that causes regressions on some hardware configurations. Might
not be due to this series either, but to some other race that this
change helps triggering.

I wonder if papering over can be acceptable downstream.

Title:
  Extremely high IOWait and processes hungs after utopic->vivid upgrade
  with Iomega Zip drive (IDE)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On Kubuntu, 64 bit AMD Phenom2 machine with 4 cores, and old (Geoforge 7025) 
Nvidia graphics.
  Using LVM. Machine also has a 2 disk software raid (mirroring).

  The machine was working fine before the upgrade, now it is almost
  impossible to use it... I see Wait in Top always above 60%; in dmesg
  after a few minutes that the machine is up even if the machine does
  nothing. I see hung processes (typically vgs, but occasionally also
  others).  LVM related commands (e.g. lvdisplay) almost always hung at
  the terminal. I also see in ps some kernel workers almost constantly
  stuck in D state. Also, the machine takes ages to shutdown.

  Issue remains there also if I disable X (switch off the X login
  manager, sddm) and check at the console.

  Sorry I cannot provide details with apport, but the machine has been
  switched off and I will not be able to take it up again before a few
  days from now.

  The symptom I am observing may also be a sign of failing hardware, so
  please leave the bug as unconfirmed until I make some more tests or
  someone provide details on similar issues. In the meantime I would
  like to see if others are experiencing a similar serious issue. Is
  there anything specific that has changed between utopic and vivid, I
  should look into?

  Hi,

  In the process of working around an issue that has appeared in the
  linux kernel after the patch series "convert host_busy to atomic_t"
  (see bug 1451277), I would like to compile kernel deb packages that
  work around the issue in a PPA, using patches that appeared on the

  Unfortunately, it is unclear to me how to build a kernel in a PPA.

  Simply taking the kernel source package, applying the patch,
  rebuilding the source package and uploading to the PPA fails to build
  in the PPA (due to ABI checks, I believe).

  I have not been able to find any up to date instruction on how to
  create a kernel source package with just a trivial patch on top of the
  current ubuntu kernel and build it in a PPA.

  - Instructions in
  https://wiki.ubuntu.com/Kernel/Dev/KernelBuildScripts do not seem
  recent and appear to involve much more than what is needed for my
  case. Most important, they fail at the invocation of the build-mkppa
  command.

  - Instructions in http://ubuntuforums.org/showthread.php?t=1682345
  seem to work, but they are very unofficial and look like black magic.
  Specifically, what are those parameters supposed to do and why are
  they needed? Why do these parameter make the built kernel a very
  different size than the original one? A minor patch should not make
  this difference.

  Altogether, can up to date, official instructions for building the
  Ubuntu kernel + a patch in a PPA be added somewhere?

  Thanks!

[Kernel-packages] [Bug 1435040] Re: Ubuntu Phone (BQ E4.5) does not connect to car-bluetooth

[Simon Fels]

@Nephilim1973: No, we can't "learn" anything here from Android. We have
a completely different bluetooth stack which you can't compare with the
Android one. Config files in /etc/bluetooth/*.conf don't help. Those
problems are at other layers.

> Why the BT handling is so different between Touch and Desktop ?

There are quite a lot differences:

* different BT chip
* different UI handlers
* newer kernel with updated Bluetooth stack

We're currently working quite hard to update the bluetooth stack on
Touch (which dates back to 2012) to a newer, more stable and reliable
one. Can't give any timeline yet but it will happen soon.

What I really need is a log of bluetoothd in debug mode. See
https://wiki.ubuntu.com/DebuggingBluetooth for details.

[Kernel-packages] [Bug 1269883] Re: 0b95:1790 [Asus N55SF] Bad performance of Asix Ethernet-to-USB device on USB3 port

[William GATHOYE]

For your information, last year, I reported the bug upstream at
https://bugzilla.kernel.org/show_bug.cgi?id=75381
That bug report seems still active.
It has been also reported on the initial driver page on Github
https://github.com/FreddyXin/ax88179_178a/issues/6

  0b95:1790 [Asus N55SF] Bad performance of Asix Ethernet-to-USB device
  on USB3 port

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Triaged

Bug description:
  Plugging USB-to-ethernet device ID 0b95:1790 ASIX Electronics Corp. in
  USB3 port yields slow performance, dmesg flooded with errors. Plugging
  on USB2 port, exact same situation otherwise, works well. This is
  reproducible 3 out of 4 attempts. Machine has 2 USB3 ports on the
  left, 2 USB2 ports on the right.

  ### When working (USB2 port)
  * ethernet auto-negociation is fast
  * mii-tool is fast (typical 0.05s)
  * few lines in dmesg
  * good performance

  ### When failing :
  * ethernet auto-negociation fails, then sometimes eventually works
  * mii-tool is slow (10s of seconds instead of 0.05s)

  time sudo mii-tool
  eth0: no link
  eth1: 10 Mbit, half duplex, no link
  real  0m40.014s
  user  0m0.013s
  sys   0m0.006s

  time sudo mii-tool
  eth0: no link
  eth1: 10 Mbit, half duplex, no link
  real  0m50.015s
  user  0m0.011s
  sys   0m0.011s

  time sudo mii-tool
  eth0: no link
  eth1: negotiated 100baseTx-FD, link ok
  real  0m10.051s
  user  0m0.000s
  sys   0m0.012s

  But on some attempts mii-tool is fast...
  time sudo mii-tool
  eth0: no link
  eth1: negotiated 100baseTx-FD, link ok
  real  0m0.057s
  user  0m0.011s
  sys   0m0.012s

  * DHCP eventually completes (after about 30 seconds) then ethernet works.
  * whole system behaviour feels a little sluggish (not very clear, though)
  * mii-tool still slow (10s of seconds instead of 0.05s)

  ## dmesg when failing

  Specific lines with occurrence count at random point (obtained with

[Kernel-packages] [Bug 1445458] Re: BCM4360 bcmwl-kernel-source System Freeze every few Seconds

[Seeed]

Same bug for me as well with the BCM4360 Chipset and Broadcom
6.30.223.248 bcmwl kernel source.

As soon as I turn wifi off, the freezing stops.

  BCM4360 bcmwl-kernel-source System Freeze every few Seconds

Status in bcmwl package in Ubuntu:
  Confirmed

Bug description:
  Every newer version of bcmwl-kernel-source than 6.30.223.141+bdcom-
  0ubuntu2 causes complete Freezes on my System every few Seconds.
  Removing the wl module restores the system to its normal state.
  Compiling the latest version 6.30.223.248 from the Broadcom STA Source
  makes no difference as well as using the latest Mainline-Kernel. So
  some of the changes between 6.30.223.141 and 6.30.223.248 must be
  responsible.

  Version 6.30.223.248+bdcom-0ubuntu0.1 installs without any Errors but
  as soon as the wl Module is loaded the Freezes occur. Dmesg shows
  nothing of note.

[Kernel-packages] [Bug 1490895] Re: Skylake/Broadwell/Haswell: No HDMI audio jack detection in D3

[Jerry Kao]

I tried the fail SKL system with KH2 image. The issue Ray discovered can
be reproduced without diwic's patches. So it seems not a regression
issue for this fix.

Before install patches, no matter HDMI plug or non-plug, the error in 
comment#12 could happen.
With HDMI plugging: failure rate 2/2
Without HDMI plugging: failure rate 2/3

Bug description:
  This is a long-standing bug for some Haswell, Broadwell and most
  Skylake machines.

  When the HDA audio controller is in D3, a hotplug event (i e, HDMI or
  DisplayPort being plugged in) fails to wake up the audio side so it
  never registers that something has happened.

  By having the i915 driver call directly into the hda driver, the HDA
  driver is always notified that an HDMI hotplug event has happened.

[Kernel-packages] [Bug 1269883] Re: 0b95:1790 [Asus N55SF] Bad performance of Asix Ethernet-to-USB device on USB3 port

[gouri]

Thanks William for your comment.

Reading activity following your links, there seems to be differences:

* launchpad (here): problem starts immediately, not on receiving heavy traffic. 
Adapter unusable in practice on USB3 (not even for moderate activity), always 
ok on USB2. Also, machine feels a little sluggish but no crash, kernel panic or 
hang observed. 
* github: reports dmesg but not much detail about what's wrong
* bugzilla: "transferring a huge number of files or pretty heavy files caused 
kernel panic: either I had a stacktrace displayed or the computer became 
completely unresponsive.", USB3, sometimes USB2.

Might be a different bug?

[Kernel-packages] [Bug 1490895] Re: Skylake/Broadwell/Haswell: No HDMI audio jack detection in D3

[Timo Aaltonen]

The hang is not a regression, it happens if hdmi is left plugged in when
rebooting/shutting down. It doesn't hang if hdmi is plugged in before
booting up.

This is filed now upstream:

Bug description:
  This is a long-standing bug for some Haswell, Broadwell and most
  Skylake machines.

  When the HDA audio controller is in D3, a hotplug event (i e, HDMI or
  DisplayPort being plugged in) fails to wake up the audio side so it
  never registers that something has happened.

  By having the i915 driver call directly into the hda driver, the HDA
  driver is always notified that an HDMI hotplug event has happened.

  Leave the car and disconnect
  Place a call
  The audio starts out using the phone as expected, after a few seconds the

  Shuts down when supposed to suspend as a reaction to self-caused
  overheat, session lost

Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  Error:
  Kernel foolishly shuts down the computer when it overheats because of the 
underlying bug "Overheat due to slow fans when on 'auto'" 
  ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689 ).
  /var/log/kern.log
  W500 kernel: [1448.648529] thermal thermal_zone1: critical temperature 
reached (100 C), shutting down
  (Hardware is ok: when the fan is forced to full speed, no overheating.)

  Consequence:
  Shutting down destroys session in Ubuntu, Gnome, and all applications that 
can't remember their latest conscious state (most applications).

  Attempted repair, failed:
  Laptop has suspending ability, but I can't find the setting for the kernel to 
make the computer suspend instead of shutting down.

  Repair suggestions:
  1. Persistence of session, so that everything would reappear after the 
restart. (this would also make updating less disruptive)
  2. Do not heat the machine like crazy; speed up fans or slow down processes. 
(fix the slow fan bug affecting Lenovo Thinkpads and fix thermald failing to 
throttle CPU)
  3. Put the computer to suspend when it's too hot.

  The problem has remained the same from at least Ubuntu 11.10 through
  14.04 .

[Kernel-packages] [Bug 1255531] Re: Daily, random hard freeze/lock up during idle since 13.10

[Xiaochuan Yu]

My laptop freezes after idling over night at lockscreen. I have Lenovo y410p on 
Ubuntu 14.04.
So far I've been able to "revive" it by going into tty (ctrl+alt+f2) and then 
do `unity start` which prints some some errors and then brings me to the 
lockscreen not frozen. The first time I login, screen will flash black for a 
sec and brings me back to lockscreen and I login again and it works (strange).
I haven't tried disabling CPU Power Management yet.

Title:
  Daily, random hard freeze/lock up during idle since 13.10

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Since about the final version of 13.10 (using it since Beta 2), my
  Lenovo L420 which was running stable until then randomly hard
  freezes/locks up about once a day while idling.

  It never happens while I am using the PC, only when I am away. It
  sometimes runs through a whole night, and sometimes it freezes when I
  leave it idle for just an hour or so. Once it froze while the screen
  was not blank yet, same situation.

  I have tried to disable power management in KDE and run without
  external screen and external harddisks, just on battery with nothing
  connected, then it also happens.

  The screen is usually blank, there is no reaction to either mouse or
  keyboard, switching to a console not possible, connection through VNC
  or SSD not possible. I need to hard-shutdown by long-pressing the
  power button.

  There is nothing in dmesg or syslog, it just ends and continues with
  the restarts. No kernel panics or something like that.

  Any advice on how to trace down the issue or similar experience?

This bug is due to a newer release of the kernel in precide-updates than
trusty-updates, but it will only occur if you have both the "precise"

[Kernel-packages] [Bug 1477171] Re: Enable intel_pstate by default on Trusty EC2 AMIs

[Craig Watcham]

We have tested the patched kernel on one network intensive (high packet)
workload with max_cstate=1 and ondemand governor disabled and it has
lower network throughput than the default kernel had with
intel_pstate=enable. There also appears to be a futex performance issue
with the c4.8xlarge which we are still investigating and may be
contributing to the problem.

  Enable intel_pstate by default on Trusty EC2 AMIs

Status in linux package in Ubuntu:
  In Progress

Bug description:
  Please can the intel_pstate driver be enabled by default on the Ubuntu
  EC2 AMIs. On instances with support for C-states and P-States [1]
  there is a notable performance impact and lack of support for higher
  clock frequencies available due to the use of the acpi-cpufreq driver.
  For example on a c4.8xlarge the default frequency is limited to 2.9GHz
  when 3.2GHz is supported by the chip [2]. Some additional analysis is
  available here [3] and re-enabling it by default has been discussed
  [4] but this request is specifically for the EC2 AMIs.

Bug description:
  While testing Ubuntu 15.10 Wily Werewolf (development branch) 64bit we
  found that kvp, vss and fcopy daemons aren't active after install.

  Repro rate: 100%
  Repro details:
  Hyper-V: Server 2012 R2
  Daily build version: 2015.08.31

  What we did: 
  root@ubuntu:~# apt-get install linux-tools-`uname -r`
  root@ubuntu:~# apt-get install linux-cloud-tools-`uname -r`

  
  In the install logs I found the following lines:

  hv-fcopy-daemon.service is a disabled or a static unit, not starting it.
  hv-vss-daemon.service is a disabled or a static unit, not starting it.
  hv-kvp-daemon.service is a disabled or a static unit, not starting it.

  
  After reboot, the kvp, vss and fcopy daemons should have started. All of them 
are inactive (dead) instead.

  root@ubuntu:~# systemctl status hv-kvp-daemon.service
  ? hv-kvp-daemon.service - Hyper-V KVP Protocol Daemon
 Loaded: loaded (/lib/systemd/system/hv-kvp-daemon.service; disabled;

  The solution is to start each of them manually. The bellow applies to vss and 
fcopy daemons too.

Title:
  Enhancement request: please document how to build kernel in PPA

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  In the process of working around an issue that has appeared in the
  linux kernel after the patch series "convert host_busy to atomic_t"
  (see bug 1451277), I would like to compile kernel deb packages that
  work around the issue in a PPA, using patches that appeared on the
  LKML.

  Unfortunately, it is unclear to me how to build a kernel in a PPA.

  Simply taking the kernel source package, applying the patch,
  rebuilding the source package and uploading to the PPA fails to build
  in the PPA (due to ABI checks, I believe).

  I have not been able to find any up to date instruction on how to
  create a kernel source package with just a trivial patch on top of the
  current ubuntu kernel and build it in a PPA.

  - Instructions in
  https://wiki.ubuntu.com/Kernel/Dev/KernelBuildScripts do not seem
  recent and appear to involve much more than what is needed for my
  case. Most important, they fail at the invocation of the build-mkppa
  command.

  - Instructions in http://ubuntuforums.org/showthread.php?t=1682345
  seem to work, but they are very unofficial and look like black magic.
  Specifically, what are those parameters supposed to do and why are
  they needed? Why do these parameter make the built kernel a very
  different size than the original one? A minor patch should not make
  this difference.

  Altogether, can up to date, official instructions for building the
  Ubuntu kernel + a patch in a PPA be added somewhere?

  Thanks!

  Please can the intel_pstate driver be enabled by default on the Ubuntu

Title:
  "lsusb -v" as root freezes the kernel on Acer ES1-111; also freeze on
  shutdown

Status in linux package in Ubuntu:
  Triaged

Bug description:
  reproducible: always

  Steps to reproduce:
  - open a terminal
  - sudo bash
  - lsusb -v

  In a virtual terminal, the command prints the name of the first device
  it finds, then the system freezes completely. In a terminal of the
  desktop, I don't even get the name of the device, the system freezes
  immediately. Either way, I have to power off the machine. There is no
  kernel oops. Nothing is written to the log. The magic sysreq key
  yields no response, although I have verified that it works before
  triggering the freeze.

  I've narrowed down the problem by calling "lsusb -v -s ". The
  system freezes on both devices of bus 3 (003:001 and 003:002). For all
  other devices, it prints the expected output and continues to work.
  When calling lsusb as a regular user, I get "Couldn't open device,
  some information will be missing", then the regular output, and the
  system keeps running. Therefore I assume that the problem is somewhere
  in the kernel, when the devices are accessed.

  This is a regression. It used to work in 14.10, and fails to work since 15.04.
  It also used to work in 14.04.2, and fails in 14.04.3.
  It fails with mainline builds 4.2.0-rc6-unstable, 4.2.0-rc2-unstable, 
4.1.0-rc2-vivid. (yeah, I've been trying for a while :-)

  Incidentally, the shutdown sequence also freezes with the kernels that
  exhibit the problem; but I cannot be sure that the cause is the same.
  I decided to first chase the USB freeze, because it was easier to
  gather information about that.

[Kernel-packages] [Bug 1436940] Re: Atheros wifi 168c:0041(QCA6164) is not supported

[robert]

I see there was no reply, if you look at the top it says this bug is for
that type card. But it is not in the Kernel yet, looks like 4.3 might
have it ready. You have to do the work around described above. It did
not work for me, but I have seen some config info from any successful
results, and there is always some variation to my situation Lenovo
G50-45 with that type card.

See this link for info on this specific card in Fedora bug group and
links to next Kernel info.

[Kernel-packages] [Bug 1475166] Re: Ubuntu 15.04 Install Error with Avago Controller

[Bryan Quigley]

@kashyap-desai thanks for checking.  AFAICT it's been at 1024 for at
least the 14.04 release as well.

Thanks for noting what FW status 0x3 means, that will help any future
tests we do.

Bug description:
  Hello Canonical Team

  We are running to an issue installing ubuntu PPC64LE 15.04 full blown
  image on our servers  (with RAID controller).  Installation hangs
  around 70% of progress.

  An important part of our configuration is Avago RAID controller:
  9361-8i Firmware version we used is 4.300.00-4429, and the package is
  24.10.0-0002.

  IMPORTANT: It has to be noted that with same hardware configuration
  14.10 full blown image installs fine.

  Dmesg logs are attached:

  Looking at dmesg logs point out that:
  LSI (avago) driver loads fine
  During further interaction with raid volume during the installation process, 
firmware errors are seen 
  [  196.991417] megasas: FW status 0x3

  [  196.999376] megasas: FW status 0x3

  [  197.007376] megasas: FW status 0x3
  Further down the  process I/O errors are thrown

  [  217.438686] Buffer I/O error on device sda2, logical block 22052867

  Full dmesg log is attached. Snippet is pasted below highlighting:

  It can be noted that there’s a Mellanox Connectx 3 pro card with some test 
Firmware on our setup. 
  We can Ignore any diagnostic messages from that card in dmesg logs for the 
purpose of this bug. 

  Thanks

Bug description:
  Currently the settings app registers an agent instance against BlueZ

  To provide a better user experience we need a different place to
  implement the agent to have it running in the background all the time.
  indicator-bluetooth sounds like a suitable component for this but we
  need to sort out how we present the different user interface screens
  (trusted helper, notifications, units8, ).

[Kernel-packages] [Bug 1485057] Re: "lsusb -v" as root freezes the kernel on Acer ES1-111; also freeze on shutdown

[Roland Weber]

For the records, here's a screenshot (photo) of the system after a freeze. 
Series of actions to get there:
1. enable kernel debug output
2. detach external mouse, to verify that messages appear
3. hit enter to get a new prompt line
4. trigger the freeze with "lsusb -v"
lsusb prints the name of the device it's going to work with. Then nothing 
anymore.

Title:
  "lsusb -v" as root freezes the kernel on Acer ES1-111; also freeze on
  shutdown

Status in linux package in Ubuntu:
  Triaged

Bug description:
  reproducible: always

  Steps to reproduce:
  - open a terminal
  - sudo bash
  - lsusb -v

  In a virtual terminal, the command prints the name of the first device
  it finds, then the system freezes completely. In a terminal of the
  desktop, I don't even get the name of the device, the system freezes
  immediately. Either way, I have to power off the machine. There is no
  kernel oops. Nothing is written to the log. The magic sysreq key
  yields no response, although I have verified that it works before
  triggering the freeze.

  I've narrowed down the problem by calling "lsusb -v -s ". The
  system freezes on both devices of bus 3 (003:001 and 003:002). For all
  other devices, it prints the expected output and continues to work.
  When calling lsusb as a regular user, I get "Couldn't open device,
  some information will be missing", then the regular output, and the
  system keeps running. Therefore I assume that the problem is somewhere
  in the kernel, when the devices are accessed.

  This is a regression. It used to work in 14.10, and fails to work since 15.04.
  It also used to work in 14.04.2, and fails in 14.04.3.
  It fails with mainline builds 4.2.0-rc6-unstable, 4.2.0-rc2-unstable, 
4.1.0-rc2-vivid. (yeah, I've been trying for a while :-)

  Incidentally, the shutdown sequence also freezes with the kernels that
  exhibit the problem; but I cannot be sure that the cause is the same.
  I decided to first chase the USB freeze, because it was easier to
  gather information about that.

  This is a long-standing bug for some Haswell, Broadwell and most

  When the HDA audio controller is in D3, a hotplug event (i e, HDMI or
  DisplayPort being plugged in) fails to wake up the audio side so it
  never registers that something has happened.

  By having the i915 driver call directly into the hda driver, the HDA
  driver is always notified that an HDMI hotplug event has happened.

[Jerry Kao]

One additional information for comment#17

When verified fix patch, audio icon disappeared once after reboot system
with HDMI connected. Please refer attached screenshot and log. Can not
recover this issue by reboot/power off system.

After recover the system and check the clean system without patch, can
not reproduce this issue anymore.

Without patch
reboot for 5 times: can not reproduce
power off for times: can not reproduce

With patch
reboot for 5 times: can not reproduce
power off for times: can not reproduce

Conclusion
There is no evidence that the audio icon disappear issue is a regression of 
this fix patch.

[Kernel-packages] [Bug 1480615] Re: [Dell Latitude E6540] ALPS touchpad and buttons work only in a single window.

[Philippe Ombredanne]

So here is where I am now with the latest kernel update from a few days
ago and everything up-to-date apt-get wise:

$ uname -a
Linux COMPUTER 3.16.0-48-generic #64~14.04.1-Ubuntu SMP Thu Aug 20 23:03:57 UTC 
2015 x86_64 x86_64 x86_64 GNU/Linux

As mentioned above, when I reboot, xinput report an incorrect device and
there are various issues with using the touchpad. I am doing a :

modprobe -r psmouse && modprobe psmouse

After that xinput reports AlpsPS/2 ALPS DualPoint TouchPad correctly and
from that point on, things are working mostly fine.  Now and then if the
touchpad stops working correctly, things are resolved by pressing Fn+F5
twice (effectively disabling then enabling the touchpad).

If I ever go in suspend mode, I need to always press Fn+F5  twice to get
a functional touchpad.

Please advise on the next setps I should take.

  [Dell Latitude E6540] ALPS touchpad and buttons work only in a single

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This is a kernel that has these recent ALPS related patches:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258837

  So after a reboot the touchpad and button work fine, at start.

  After a while the buttons, a single tap click, a double tap-click and
  the dual finger scrolling stop working on the correct front-most
  window and work instead on a background window.

  If I Alt-tab to bring the window that receives the touchpad events to
  front, it receives it ok,  so this one window gets mouse events. Using
  either the touchpad or the glidepoint is then limited to this window
  at this point.

  Going to a terminal with ctrl-alt-f1 just a few seconds and then back
  to ctrl-alt-f7 restores things to normal for a while. Until its starts
  again. No dmesg nor syslog show up.

  My system is locking up, while using Mozilla FireFox, after installing latest

  I can use Ctrl-Alt-Bsp to kill the instance of FF, but this re-occurs now

  Could this be a problem with kernel handling of Nvidia graphics?  I have 
older 8600 graphics.  Other

  Again, no problems with this system until a few days ago when I upgraded to 
latest kernel.
  I always install all system updates as soon as I receive notice.

  Any way to get back to older kernel?  No previous kernel updates
  caused any problems!

  Thx.

  Hi, 
  I have a PCI card to receive DVB television on my desktop computer.
  The card works, but only if I restart the computer from Windows.

  I believe that Windows initializes something that does not get erased when 
the computer restarts, 
  and Ubuntu does not initialize this when it boots.
  This initialization gets erased when Ubuntu goes to sleep too.

  Please let me know any command that I could run to see differences
  between the card's configuration when it works and when it doesn't.

[Kernel-packages] [Bug 1493143] [NEW] rtl8723be wifi unusable on lenovo ideapad y50-70

[Henk Stubbe]

Public bug reported:

I obtained a lenovo y50-70 a few weeks ago, and installed ubuntu 14.04.3
LTS on it (dual boot with windows 8 that came pre-installed).

$ lsb_release -rd
Description:Ubuntu 14.04.3 LTS
Release:14.04

I have not been able to get the rtl8723be wifi adapter to work yet.

If it will connect to a wifi network at all (which is rare), it will be
choppy (10% to 50% packet loss on a ping to the default gateway) and
usually disconnect after a few minutes.

The internet suggests a few work-arounds:

- run with fwlps=0 ips=0 as options to the rtl8723be module (eg. 
http://askubuntu.com/questions/590414/wifi-problems-with-rtl8723be-in-ubuntu-14-04)
- install an alternative driver (eg. 
http://askubuntu.com/questions/590414/wifi-problems-with-rtl8723be-in-ubuntu-14-04)
http://paste.ubuntu.com/1230961

However, none of those suggested worked for me.

I have tried downgrading the kernel down to 3.13.0-62, and various
kernels in between, but none of that helped either.
