Same issue
Interesting thing, i got that errors, but all work fine, except
libvirt/qemu/kvm, my VM didn't start.
I go to logs and see that errors about i915 and suggest to restart libvirtd
daemon, and when i stop admin socket ( meaning: sudo systemctl stop
libvirtd-admin.socket ) system hangs
I can confirm the same bug on my side

I'm a bit hesitant to mention this as it may be a red herring - and my
system has been stable and not hung due to pure coincidence - but I
installed an OEM kernel yesterday and haven't experienced my regularly
scheduled daily hang since:

@oded, thanks for the message!
Maybe it's a different bug, however I think that the bug is still very close.
If you look at the original poster's dmesg output, you see that the freezes
(reported by the "hang" message) also occur multiple times.
The only difference is that the frequency is about
@sanette - the problem you describe doesn't seem to be the same problem

Here is an interesting observation (I think). I have a demo program that
makes strong use of the GPU. Here is what happens with two close kernel

=> I CAN HEAR COIL NOISE when running the demo! And the whole
I have the same issue here, random freeze, espacially when working hard
on the video card.
I'm a bit worried because they claim here that 5.4.0 does not solve it

** Bug watch added: Linux Kernel Bug Tracker #205545
Unfortunately I can't upgrade from 5.4.0 so I added the following to
/etc/modprobe.d/modesetting.conf
options i915 modeset=1 reset=1
See other options with modinfo i915
This seems to have made the problem occur less frequently.

Just had an i915 crash on 5.4.0-14-generic #17+lp1853044v1. There appear
to be 3 crashes right after the other, I'm not sure what it means. It
could be related to the fact that I have a script running that detects

Bugs,
@David - as far as I know, before reporting kernel issues, Ubuntu users
are expected to try a repro with a mainline kernel. I've read (some of)
the discussion in the Freedesktop bug report where people have proposed
that various patches have possibly solved the problem, so I hit the
mainline PPA
I just got the same freeze with the mainline 5.4.22. I'm trying the
proposed kernel.

Oded, we have a new kernel in focal-proposed (5.4.0-15.18) which

we'll definitely have the 5.4.22 updates in the next kernel we upload.
