@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 🤷) - 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
