[Kernel-packages] [Bug 1868551] Re: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire
Regarding #28
"on 20.04 LTS and v5.6 is not working properly with WiFi."
When I first tested Kernel 5.6 branch, the WiFi was broken because of this:
https://linuxreviews.org/Linux_5.6.2_Is_Released_With_Intel_Wifi_Fix
Now it is working again with the current 5.6 branch.
Kernel 5.5 is now EOL (as of 5.5.19 end of April)
https://en.wikipedia.org/wiki/Linux_kernel_version_history#Releases_5.x.y
Intel should do better QA for their iGPU and WiFi
and try to port it to all stable LTS branches aka 5.4.x and 5.6.x
If you still have issues with Intel i915 on 5.4.x, you can use
the following one-liner to install 5.6.x
which curl >/dev/null 2>&1 || sudo apt-get install -qq -y curl; for
version in $(curl -sL https://kernel.ubuntu.com/~kernel-ppa/mainline/ |
tac | grep -Pom1 '(?<=")v5\.6\.[0-9]+/'); do for deb in $(curl -sL
https://kernel.ubuntu.com/~kernel-ppa/mainline/${version} | grep -Pom4
'(?<=")linux-(headers|image-
unsigned|modules)-5\.6\.[^"]+[0-9]+(-generic_5\.6\.|_5\.6\.)[^"]+.(amd64|all)\.deb');
do curl -sLo ${deb} https://kernel.ubuntu.com/~kernel-
ppa/mainline/${version}/${deb}; debs="${debs} ${deb}"; done; sudo dpkg
-i ${debs}; done
If you need to go back to legacy Ubuntu 20.04 LTS Kernel and remove
Linux Kernel 5.5 and 5.6
dpkg --get-selections | awk '/linux-.*-5\.[5-6]/ { print $1 }' | xargs
echo sudo apt-get purge -y

Title:
Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4)
i915_active_acquire
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Focal:
Fix Committed
Bug description:
SRU Justification:
[Impact]
Users are experiencing a frequent NULL pointer dereference crash in
i915_active_acquire when using kms, which is used by default.
[Fix]
The fix is a cherry pick from upstream which was supposed to be backported to
5.4 by upstream, but was neglected. The fix has a subsequent Fixes patch to
resolve some uninitialized pointer usage.
[Test]
Verified by multiple bug reporters.
[Regression Potential]
Medium. Although there are a lot of lines added, they're mostly boilerplate,
and this patch is confirmed by multiple users to fix a crash.

I tested the test kernel 5.4 for about a day without issue but all my computers using Intel GPU are using by default kernel 5.5. I don't want to change that.

[Kernel-packages] [Bug 1868551] Re: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.32/CHANGES https://patchwork.ozlabs.org/project/ubuntu- kernel/patch/20200407222740.7671-2-sultan.alsa...@canonical.com/ Note that this bug only affects 5.4 and has since been fixed in 5.5. Normally, a backport of the fix from 5.5 would be in order, but the patch set that fixes this deadlock involves massive changes that are neither feasible nor desirable for backporting [1][2][3]. Therefore, this small patch was made to address the deadlock specifically for 5.4. ** Information type changed from Private to Public -- 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/1868551 Title: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire Status in linux package in Ubuntu: Confirmed Bug description: uname -a Linux xps 5.4.0-14-generic #17-Ubuntu SMP Thu Feb 6 22:47:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux lsb_release -a No LSB modules are available.

[Kernel-packages] [Bug 1868551] Re: Screen freezes : NULL pointer dereference i915_active_acquire since Linux 5.4
Seems to be fixed in the latest 5.5
http://kobi.wang/v5.x/ChangeLog-5.5
drm/i915: Hold reference to intel_frontbuffer as we track activity
Since obj->frontbuffer is no longer protected by the struct_mutex, as we
are processing the execbuf, it may be removed. Mark the
intel_frontbuffer as rcu protected, and so acquire a reference to
the struct as we track activity upon it.
Closes: https://gitlab.freedesktop.org/drm/intel/issues/827

I am not sure that is a good idea to ship Ubuntu 20.04 LTS with Linux
Kernel 5.4 branch unless you backport 5.5 patches as many people rely on
bult-in Intel GPU in their workstation and the Intel graphics kernel
driver is not very stable

[Kernel-packages] [Bug 1536567] [NEW] i915 stop working after linux 4.2.0-21-generic
Public bug reported: Hello, After updating the linux kernel of my Ubuntu 15.10 from 4.2.0-21 to 4.2.0.22 I was unable to get to XFCE and slim login manager, I was stuck on a black screen with nothing displayed (no text/graphics). Same issue with latest 4.2.0.25. When I go back to 4.2.0-21 everything is working perfectly. So something is "broken" with i915 module starting 4.2.0.22 and newer. After some research online, I managed to make it work even with kernel 4.2.25 by doing this vodoo magic magic. It's not clear what made it work ;-P # /etc/default/grub GRUB_CMDLINE_LINUX="libata.force=noncq quirks.mbp_force_ahci=1 acpi_backlight=vendor apple_bl.use_gmux=1 reboot=pci i915.enable_ips=0 i915.i915_enable_fbc=1 i915.i915_enable_rc6=1 i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0 intel_pstate=disable" # /etc/modprobe.d/i915.conf options i915 semaphores=1 # /etc/modprobe.d/blacklist blacklist intel_pstate reboot lsb_release -a No LSB modules are available.

@boot0user I agree with you. The best workaround for now is to update
kernel to Vivid!
# Physical Server (with EFI):
sudo apt-get -y purge linux-{headers,image}-3.16.0-48-generic
sudo apt-get -y install linux-signed-generic-lts-vivid

[Kernel-packages] [Bug 1492146] Re: igb Detected Tx Unit Hang
This bug should be a top priority because people will suffer from it as soon as
they reboot
their 14.04 LTS with an Intel Gigabit NIC and the "current" Utopic kernel
(3.16.0-48-generic).
I had the same problem with HP ProLiant DL380e Gen8 which an Intel I350 Gigabit
NIC
(Hewlett-Packard Company Ethernet 1Gb 4-port 366i Adapter)
It was hard to get a shell with 30-50% packets drop and igb driver resetting
ALL NICs...
"blind-typing" on the shell and wait 1-2 minutes to get the output... of dmesg
;-)
I updated the kernel of 14.04 LTS from Utopic to Vivid and everything is
working again.
Workaround is:
screen -S kernel
apt-get -y purge linux-{headers,image,image-extra}-3.16.0-48-generic
apt-get -y install linux-image-generic-lts-vivid linux-headers-generic-lts-vivid
reboot

I can not use "ubuntu-bug linux" because it has no options and wants to report only for the currently running kernel, which has no network connection. For some reason I can only attach one file. I chose to attach the kern.log - the version.log shows only the currently running kernel, and I can paste the lspci log later if required. > lsb_release -rd Description:Ubuntu 14.04.3 LTS Release:14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1488024/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp

[Kernel-packages] [Bug 1413540] Re: Trusty soft lockup issues with nested KVM
@arges
For me it's related at least part of it...
If I don't update the kernel to proposed-updates I have the following messages :
If I use one CPU instead of two, I don't have those messages.
BUG: soft lockup CPU#1 stuck for 22s! [qemu-system-x86:6889]

BUG: soft lockup CPU#1 stuck for 22s! [qemu-system-x86:6889]
...
My stress test is installing openstack with cloud-install on a single VM
(nested KVM)
generated with uvt-kvm and two vcpus.
The backtrace I posted is the result of a manual force off (using
virt-manager) of the test openstack VM.
shortly after cloud-install tries to launch a VM in VM, the CPU reach 100% and
all the shells (also console) get stuck
The last kernel message of the VM before I loose control is
[ 942.295014] IPv6: ADDRCONF(NETDEV_UP): virbr0: link is not ready

[Fix]
commit 9242b5b60df8b13b469bc6b7be08ff6ebb551ad3,
Mitigates this issue if b6b8a1451fc40412c57d1 is applied (as in the case of
the affected 3.13 distro kernel. However the issue can still occur in some
cases.
[Workaround]
In order to avoid this issue, the workload needs to be pinned to CPUs
such that the function always executes locally. For the nested VM
case, this means the the L1 VM needs to have all vCPUs pinned to a
unique CPU. This can be accomplished with the following (for 2 vCPUs):
virsh vcpupin domain 0 0
virsh vcpupin domain 1 1
[Test Case]
- Deploy openstack on openstack
- Run tempest on L1 cloud
- Check kernel log of L1 nova-compute nodes
(Although this may not necessarily be related to nested KVM)
Potentially related: https://lkml.org/lkml/2014/11/14/656
Another test case is to do the following (on affected hardware):
1) Create an L1 KVM
