[Bug 1861395] Re: system hang: i915 Resetting rcs0 for hang on rcs0
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 up, exactly like in author post.

@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 every 2 seconds, which makes the user feel it completely freeze all the time. In my case it was a bit less frequent, but maybe that's just because I was putting less strain on the GPU.

[Bug 1861395] Re: system hang: i915 Resetting rcs0 for hang on rcs0
@sanette - the problem you describe doesn't seem to be the same problem originally reported in this ticket: that problem was with kernel 5.4 and was causing a complete hang - not for a few seconds, but complete failure with a graphical system reset the only resolution. You may be experiencing an earlier version, and less severe, of the reported issue, on the 5.3 kernel. Regardless -it's not the exact same issue. Regarding the kernel.org bugzila comments: the fix was applied in version 5.5 and 5.6 in the upstream kernel. It was not applied to 5.4 as if yet (even though 5.4 is an LTS kernel and this is an extreme regression 路) - for the upstream kernel. But Ubuntu developers have applied the fix to the Ubuntu 5.4 kernels, at least for focal. I suggest to upgrade to the 5.4 kernel reported above to contain the fix (5.4.0-17.21 or later) and see if it solves your problem. If you are interested in continuing to run kernel 5.3 on bionic, then I suggest you open another ticket for the specific issue you are experiencing - as it is not this issue, and this issue was resolved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861395 Title: system hang: i915 Resetting rcs0 for hang on rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1861395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1861395] Re: system hang: i915 Resetting rcs0 for hang on rcs0
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
these crashes, waits 30 seconds and then restarts the display manager -
but if it is related than that means that the additional crashes were
when there was just the display manager, and that never happened to me
before.

[Bug 1861395] Re: system hang: i915 Resetting rcs0 for hang on rcs0
@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 and got the newest 5.4 :-). And it looked promising for a while.

Oded, we have a new kernel in focal-proposed (5.4.0-15.18) which includes up to 5.4.21 so it might be worth giving that a try.
