Dear Maintainer,

With the 5.10.0-29 kernel, my Dell Latitude E7250 hangs when resuming
from suspend-to-RAM.  I have not once gotten a successful resume; this
problem does not appear at all with the 5.10.0-28 kernel.

The visible symptom is that I see the display as it was at the time of
suspend, but there is no response to the trackpad or keyboard.  If
there is a screen locker that displays the time (e.g., Cinnamon), the
time-of-suspend is displayed, even when the resume happens several
minutes (or longer) after the suspend.  I have tried the following
desktop sessions: Cinnamon, i3, and maybe Xfce, too.  I've also seen
this hang after suspending from the lightdm login screen.

I have also seen the same (or at least a similar) hang a couple times
with the 5.10.0-29 kernel on a different system.  That one is a
ZaReason Limbo (AMD FX-6300 processor, Radeon graphics).  Most of the
time, though, I can resume that system okay, at least with Cinnamon
and i3.
