Package: src:linux
Version: 5.2.9-2
Severity: important
Tags: patch upstream

Dear Maintainer,

Linux 5.2 kernels contain a bug that causes short graphics freezes when using
the i915 driver on certain Intel GPUs.

The issue was originally reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=204183

A patch for 5.2 is available here:
https://patchwork.freedesktop.org/series/63774/#rev4

This patch will likely be included in kernel 5.3, but 5.2 and possibly older
kernels are also affected.

Please consider adding this patch to 5.2 until it arrives in a stable kernel.

As a temporary workaround, it's possible to disable PSR (Panel Self Refresh) by
adding i915.enable_psr=0 to the kernel command line. There may be higher power
consumption or other consequences.

Thanks!

The mentioned patch seems to have been applied to 5.2.8 and 5.3-rc3.

I guess the found version was thus wrong used in the bugreport?

I'm closing the bug now, feel free to reopen if the issue still
persisst.

Regards,
Salvatore
