Package: src:linux
Version: 5.3.7-1
Severity: normal
Tags: patch upstream

Whole machine hangs, but recovers after a few seconds; no visible
association to CPU or memory load.

Please include the patch from

https://patchwork.freedesktop.org/patch/300891/

it claims to fix a bug that is reported since about a year in many different
bug reports and -trackers.

Forgot to mention: The main symptom is in dmesg

i915 <pci-device> Resetting chip for hang on rcs0

Here are a few bug reports that seem to match:

AFAICS, the patch was not applied, but could you confirm if the issue
still persist with recent kernel?

With 5.10.0-6-amd64 I don't have this message anymore;
when resuming there's a few seconds wait before the screensaver
login window comes up, and I get these messages in kern.log:

Perhaps that's related.
