Title:
HP ProLiant m400 Server sda timeout causes file system hang
Status in linux package in Ubuntu:
Triaged
Bug description:
While running stress-ng on a ProLiant m400 Server I managed to cause
the disk controller to timeout which causes a file system hang. I am
wondering if the timeout was causes because I completely overloaded
the system causing it to be slow on ata handling times.
I ran:
stress-ng --all 64 -t 600 -v
and the machine slowly clogged up with stress processes, and finally
hit the hang. Had to reboot the system.
Attached is a kernel log.

Michael Greene, it will help immensely if you filed a new report via a terminal: ubuntu-bug linux Please feel free to subscribe me to it. ** Summary changed: - Display is heavily distorted after kernel upgrades + 8086:0152 [Dell OptiPlex 9010] Display is heavily distorted after kernel upgrades -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1251580 Title: 8086:0152 [Dell OptiPlex 9010] Display is heavily distorted after kernel upgrades Status in linux package in Ubuntu: Triaged Bug description: The bug is present already at boot (even from a USB stick boot without installing) in all Ubuntu (and variants) relying on Linux kernels 3.10 to 3.12 (- still present in 3.13). Because it's so easy to boot via USB, I tried it on 7 computers (all of them Dell Optiplex 9010). The upshot is that old distros boot correctly, with working displays. The new 13.10 distros doesn't work (i.e. the display is distorted) on 3 computers. On my computer (which is one of the 3 malfunctioning), recovery mode also always display correctly. Playing around with xrandr and the xorg.conf turoned out to be of no avail. I tried changing the Linux kernels (after indications from this Ubuntu forums thread: http://ubuntuforums.org/showthread.php?t=2186873 ). It turns out that kernels of version = 3.9 are OK. Kernels = 3.10.19 are not OK. I'm willing to bisect in the 3.10.x range if deemed of interest. I kept the lshw, lspci, xdpyinfo, ddcprobe and Xorg.0.log of all these 7 boots from USB stick. I put all those log files in a zip file availiable at http://dfiles.eu/files/njfpo8b4k Here are the main differences I found in those files (except the Xorg.0.log which are not so handy to compare as the beginning of lines are always different). I guess that the most telling is the following line from ddcprobe. For non-correctly-displaying computers: dtiming: 1920x1080@68 For correctly-displaying computers: dtiming: 1920x1080@60 For the record, there is no other ctiming or dtiming line in the output of ddcprobe. The configuration are otherwise strikingly similar. The other differences which seemed of significance (i.e. not mentionning hard drives partitions and serial numbers) is that uncorrectly working computers have the following extra line in lspci 00:16.3 Serial controller: Intel Corporation 7 Series/C210 Series Chipset Family KT Controller (rev 04) Correspondingly, the lshw of these computers have the following extra section: *-communication:1 description: Serial controller product: 7 Series/C210 Series Chipset Family KT Controller vendor: Intel Corporation physical id: 16.3 bus info: pci@:00:16.3 version: 04 width: 32 bits clock: 66MHz capabilities: pm msi 16550 bus_master cap_list configuration: driver=serial latency=0 resources: irq:19 ioport:f0e0(size=8) memory:f7d3a000-f7d3afff Lastly, in the *-pci section. Also, the *-memory *-bank:n (for n an integer) are not of the same vendor (Samsung or Nanya technologies for correctly-displaying computers and Hynix/Hyundai for non-correctly- displaying ones). The visual distortion is roughly as follows: every line gets horizontally enlarged by a factor t. This factor varies with time and with the height of the line to make nice sine curves out of straight vertical lines. Actually there is a phase difference between even and odd lines. The leftmost part of the screen remains legible as the distortion effect is smaller there but the rightmost part is impossible to read. A straight vertical line looks like sine wave, the time frequency of this wave varies with time, the amplitude is always increasing linearly as one moves to the right of the screen.

Samuel Bushi, the next step is to fully reverse commit bisect from kernel 3.13 to 4.1 in order to identify the last bad commit, followed immediately by the first good one.

Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Ballooning works. Hot Add has issues. The original issue as reported has been resolved. Initially, memory is successfully hot added to the VM.

[Kernel-packages] [Bug 1453812] Re: System freeze when using LibreOffice Writer
This bug affects me too! Same behavior. You should consider that this is a DATA LOSS bug, just because every time the pc freezes I lost all my work not yet saved. So the importance should be set to high. By the way a bug that causes a system freeze can't be considered low importance just because the final user can't trust the distro anymore. I'm very upset with this because I use Ubuntu at job and it's not nice to waste job time. I tried to disable the use anti-alias option in Options - general - view- menu in libreoffice BUT this causes Libreoffice writer to freeze the entire system just after it was launched (after the splash screen disappears and when you are prompted to type something in the blank page). So probably it's a graphic driver problem. I have a nvidia 8500GT and I use nouveau driver. Hardware acceleration is enabled (gallium 0.4 on NV86).

Signed-off-by: Doug Ledford dledf...@redhat.com commit 6387d8d5896536b904ba6937fe019a29548e3a86 Author: Doug Ledford dledf...@redhat.com Date: Sat Feb 21 19:26:59 2015 -0500 IB/ipoib: factor out ah flushing Create a an ipoib_flush_ah and ipoib_stop_ah routines to use at appropriate times to flush out all remaining ah entries before we shut the device down. Because neighbors and mcast entries can each have a reference on any given ah, we must make sure to free all of those first before our ah will actually have a 0 refcount and be able to be reaped. This factoring is needed in preparation for having per-device work queues. The original per-device workqueue code resulted in the following error message: ibdev: ib_dealloc_pd failed That error was tracked down to this issue. With the changes to which workqueues were flushed when, there were no flushes of the per device workqueue after the last ah's were freed, resulting in an attempt to dealloc the pd with outstanding resources still allocated. This code puts the explicit flushes in the needed places to avoid that problem.

I compiled it with xlf and its corresponding OpenMP. There is no difference in performance. (2) There was a concern about NUMA, meaning is it possible the CPU binding by OpenMP is incorrect so
[Kernel-packages] [Bug 1470647] [NEW] Intel Wifi 3160 connects to AP but no internet access with 802.11n 2.4Ghz
Public bug reported: I have a Lenovo Y50-70 with Intel Wifi 3160 I can associate and authenticate with my wifi router but I have been unable to send/receive data using 802.11n 2.4Ghz on Ubuntu 14.04.2. Trying to ping the router IP address just times out. I guessed this might be fixed in the latest version of Ubuntu so I installed the daily build of 15.10 from http://cdimage.ubuntu.com/daily- live/current/ dated June 3rd but got the same results. I can access the internet using the 5Ghz band but the range is not as good as 2.4Ghz so I get very low speeds at the top of my house. All my other laptops phones can connect at 2.4Ghz at 70-150Mbit with no problems at the top of my house. I've tested with iPhones, Nexus 5, Moto X, Lenovo Thinkpads and Macbooks. I've also tested Ubuntu 14.04.2 with Kernel 4.1 and iwlwifi firmware version 13 with the same results and I've tested this using the 15.04 live cd with the same results. I've tried rfkill block bluetooth to turn off bluetooth. I have attached a file with all the necessary debug info from Ubuntu 15.10 daily fresh installation. The only output from dmesg after trying 2.4Ghz is as follows: [ 369.179441] cfg80211: Calling CRDA to update world regulatory domain [ 369.182145] cfg80211: World regulatory domain updated: [ 369.182149] cfg80211: DFS Master region: unset [ 369.182150] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 369.182153] cfg80211: (2402000 KHz - 2472000 KHz @ 4 KHz), (300 mBi, 2000 mBm), (N/A) [ 369.182155] cfg80211: (2457000 KHz - 2482000 KHz @ 4 KHz), (300 mBi, 2000 mBm), (N/A) [ 369.182156] cfg80211: (2474000 KHz - 2494000 KHz @ 2 KHz), (300 mBi, 2000 mBm), (N/A) [ 369.182158] cfg80211: (517 KHz - 525 KHz @ 4 KHz), (300 mBi, 2000 mBm), (N/A) [ 369.182159] cfg80211: (5735000 KHz - 5835000 KHz @ 4 KHz), (300 mBi, 2000 mBm), (N/A) [ 380.579257] wlan1: authenticate with f8:8f:ca:41:e3:bc [ 380.582170] wlan1: send auth to f8:8f:ca:41:e3:bc (try 1/3) [ 380.603705] wlan1: authenticated [ 380.604603] wlan1: associate with f8:8f:ca:41:e3:bc (try 1/3) [ 380.644131] wlan1: RX AssocResp from f8:8f:ca:41:e3:bc (capab=0x411 status=0 aid=8) [ 380.644699] wlan1: associated ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: 3160 intel iwlwifi wifi ** Attachment added: wireless-info.txt https://bugs.launchpad.net/bugs/1470647/+attachment/4423101/+files/wireless-info.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1470647 Title: Intel Wifi 3160 connects to AP but no internet access with 802.11n 2.4Ghz Status in linux package in Ubuntu: New Bug description: I have a Lenovo Y50-70 with Intel Wifi 3160 I can associate and authenticate with my wifi router but I have been unable to send/receive data using 802.11n 2.4Ghz on Ubuntu 14.04.2.

[Kernel-packages] [Bug 1300557] Re: Screen resolution no longer works
If you don't have time to read what I wrote, or if something I wrote is not clear, just say so and I will understand. Let's not get caught in the endless Confirmed/Incomplete circle. I'll summarise what I said before, to make it easier to digest: You asked me to bisect between 3.13.0.18.38 and 3.13.0.20.24. That latter revision is not tagged in any of the Ubuntu kernel branches I could still find. I tried all branches from Precise to Vivid, but many of them are no longer available. The closest I could find was 3.13.0-19.40. The problem started sometime *after* that version. And then we were stuck at the point where I asked for suggestions on where to find the missing version(s) so I can bisect further. Any ideas? ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1300557 Title: Screen resolution no longer works Status in linux package in Ubuntu: Confirmed Bug description: My display's native resolution is 2560×1440 pixels. Prior to, I think, Saucy I could only reach this resolution by adding it using xrandr, and then calling xrandr on boot/login to select that resolution. The Display preferences did not show any higher options than 1920×1200. In Saucy, the native resolution just worked, and I could stop using xrandr. It also worked in Trusty in the alpha releases, up to (and I think including) beta-1. But today (this is not an April's fool, is it?) I rebooted after an upgrade, and found myself back in 1920×1200. Again, the Display preferences list that resolution as the highest possible. But this time, attempts to ‘xrandr --addmode’ my native resolution failed. The error message wasn't very helpful; I'll try to reproduce it later but it throws my display into yet a lower resolution that's hard to work with.

[Kernel-packages] [Bug 1467912] Re: error ib_dealloc_pd failed when load unload ib_ipoib module
Hello Joseph, Thanks a lot for the update. Related to earlier releases. I don't think that this bug affected earlier releases. because we saw it just in kernel 3.19 (Ubuntu 15.04). Thanks, Kamal -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1467912 Title: error ib_dealloc_pd failed when load unload ib_ipoib module Status in linux package in Ubuntu: In Progress Status in linux source package in Vivid: In Progress Bug description: When we try to load and unload the ib_ipoib driver we get an error message. Steps to reproduce: load ib_ipoib: modprobe -v ib_ipoib configure ip: ifconfig ib0 11.135.196.7/16 unload driver: modprobe -rv ib_ipoib We will see this message in dmesg: [ 709.652944] ib0: ib_dealloc_pd failed uname output: root@qa-h-vrt-035:~# uname -a Linux qa-h-vrt-035 3.19.0-16-generic #16-Ubuntu SMP Thu Apr 30 16:09:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux The following two upstream commits fix this issue: commit 9ab874b6593045886b699df2bc3ff803d88a9f7c Author: Doug Ledford dledf...@redhat.com Date: Sat Feb 21 19:27:00 2015 -0500 IB/ipoib: change init sequence ordering In preparation for using per device work queues, we need to move the start of the neighbor thread task to after ipoib_ib_dev_init and move the destruction of the neighbor task to before ipoib_ib_dev_cleanup. Otherwise we will end up freeing our workqueue with work possibly still on it. Signed-off-by: Doug Ledford dledf...@redhat.com commit 6387d8d5896536b904ba6937fe019a29548e3a86 Author: Doug Ledford dledf...@redhat.com Date: Sat Feb 21 19:26:59 2015 -0500 IB/ipoib: factor out ah flushing Create a an ipoib_flush_ah and ipoib_stop_ah routines to use at appropriate times to flush out all remaining ah entries before we shut the device down. Because neighbors and mcast entries can each have a reference on any given ah, we must make sure to free all of those first before our ah will actually have a 0 refcount and be able to be reaped. This factoring is needed in preparation for having per-device work queues. The original per-device workqueue code resulted in the following error message: ibdev: ib_dealloc_pd failed That error was tracked down to this issue. With the changes to which workqueues were flushed when, there were no flushes of the per device workqueue after the last ah's were freed, resulting in an attempt to dealloc the pd with outstanding resources still allocated. This code puts the explicit flushes in the needed places to avoid that problem.
