Control: retitle -1 i915 workqueue issue / i915_hotplug_work_func __flush_work.cold.53
Hi sanshu,
thank you for your interest in making Debian better and filing this
report:
* sanshu <sanshu.su@gmail.com> [200830 22:46]:

[..]
Other discussions on f.e. the Fedora bug tracker suggest that this
has been fixed in Linux kernel 5.3 or 5.4. Can you please try with
one of those versions (or just the current Debian 4.19) and see if
the problem goes away?
If the problem persists in 4.19, but is gone in 5.3/5.4, it might be
useful to "git bisect" to find the fix. Maybe it can be included in
a buster update, then.
Chris
