[Bug 1868551] Re: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire
Recently installed a brand new copy of Linux Mint 20 Cinnamon and suffered frequent freezes. The workaround suggested in comment #45 fixed these for me. My current kernel is 5.4.0-47-generic, and I'm using a Intel© Core™ i5-6500T CPU (2.50GHz × 4) with Intel Corporation HD Graphics 530. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868551 Title: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1868551/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

CubicSDR still triggers it for me even in 5.4.0-42.46, further a 5.8.0 mainline kernel also suffers the same.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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

On my computer I use the workaround of changing the Xorg session from modesetting to intel. To do this, firstly checking if xserver-xorg- video-intel is installed and then I create the file /etc/X11/xorg.conf.d/99-intel.conf with the following content: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "DRI""3" EndSection Then I restart the display manager to apply the change.

Tried the kernel by @lordbaco in #33 and it doesn't improve anything, just in case it's useful. My machine freezes up after a few hours, usually at a point where the fans start to spin up under load. 2-3 times a day. The symptoms are that the cursor starts to lag, massively, and the whole machine gets less and less responsive until it freezes. I didn't have any luck with the kernel in #40 as it wouldn't boot for me. If you have any pointers to booting with it then I'll happily try.

@leozinho29-eu The kernel from comment 34 was just a plain 5.4.0-26
kernel, with nothing added to it (which wasn't intentional). Could you
reproduce the atomic update failure messages with an official Ubuntu
kernel installed, and then create a new launchpad bug for it?
Given that you encountered the atomic update failures with comment 34's
kernel, which was just an unmodified Ubuntu kernel, I don't think the
problem is related to the fix for this bug.
The bisect from your duplicate doesn't make sense, but I think there's a
reasonable explanation for that. This kernel panic is caused by a race,
so any changes to code that could affect the timing of the GPU driver's
code execution, in some indirect way, could either exacerbate or
alleviate the crash.
That said, there is a clear diagnosis for this bug, and it is definitely
fixed by the upstream commit da42104f589d ("drm/i915: Hold reference to
intel_frontbuffer as we track activity").

[Bug 1868551] Re: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire
For now (1 hour and 40 minutes running glxgears in one screen), the system hasn't crashed. With the following command line: BOOT_IMAGE=/boot/vmlinuz-5.4.30+ root=UUID=6b4ae5c0-c78c-49a6-a1ba- 029192618a7a ro quiet ro kvm.ignore_msrs=1 kvm.report_ignored_msrs=0 kvm.halt_poll_ns=0 kvm.halt_poll_ns_grow=0 i915.enable_fbc=0 i915.enable_gvt=1 resume=UUID=a82e38a0-8d20-49dd-9cbd-de7216b589fc log_buf_len=16M usbhid.quirks=0x0079:0x0006:0x10 mtrr_gran_size=64M mtrr_chunk_size=64M nbd.nbds_max=2 nbd.max_part=63 cgroup_enable=memory swapaccount=1 The crash hasn't happened, but the Atomic update failure messages are still present and happening relatively often. Strange how the kernel from command 34 was fine until i915.enable_fbc=0 was set. By the way, does the bisect from the duplicate make sense? I found the result strange, but it seemed to fix it to me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868551 Title: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1868551/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
