--- Comment #16 from Jan Schreiber <jan@mecinus.com> ---
I ran into the same issue with my ThinkPad x250. Resume always worked with
12.2. On FreeBSD 13, resume seems not to work when the uptime is more than a
couple of hours. Sleep time does not seem to make any difference.

I'm running drm-fbsd13-kmod-5.4.92.g20210419 and 13.0-RELEASE-p1. I also set
hw.usb.no_suspend_wait=3D1 as suggested here:

tml
Makes no difference.

Have you guys found any fix other than downgrading to 12.2? Or any ideas on=
 how
to debug this problem? Or does anybody know where to find the code that han=
dles
resume?
