Subject: REGRESSION with 5.14: Resume not working on Toshiba notebook

Hello,

on my old Toshiba notebook the system crashes on wakeup (resume) after
suspend to memory (echo mem > /sys/power/state). The system is
inaccessible from remote. The only way to get it working again is to
hard power off and on.

Kernel 5.13.13 works fine, 5.14 does not. When disabling DRM_I915 in
the kernel configuration, 5.14 works fine too, so I have posted this
error with all further infos on

https://gitlab.freedesktop.org/drm/intel/-/issues/4049

Until now I got no response. Any help would be appreciated.

Regards
Andreas Friedrich
