Hi
I'm now experiencing this bug with
Samsung SSD 970 EVO Plus 2TB on a Lenovo T480 with 2 nvme drives.
nvme_core.default_ps_max_latency_us=0 does not help it.
Because the problem only arose after two months, I can't rule a hardware
failure, although smart looks all fine.
Some relevant info

Hi
I'm not sure if I can disable frambuffer compression (FBC).
> cat /proc/cmdline
says I disabled it:

but
> systool -v -m i915 |grep fbc
says I did not:
Dear Daniel,
Thank you for that work-around!
The error message is a bit odd, as it says that it may lead to LESS powersaving.
Even then, once hibernated there is no power draw anyway

Title:
brightness setting and sleep/suspend
Confirmed on a T480.
I lose my trackpoint mouse after a failed hibernation attempt, and can
suspend to ram anymore.
