Thanks for going back to me!
With 6.8.9, either echo disk > /sys/power/state do nothing at all
or (when repeated) it cause a kernel panic.
Despite the panic, after a hard reboot, the system resume from hibernation,
exactly as
if echo disk > /sys/power/state had worked.
With 6.12.86, this is completly different.
echo disk > /sys/power/state suspends the system.
the system resumes correctly but immediatly stop.
after a reboot it resumes again and then fails immediately
I attach data for
uname -a
Linux seventeen 6.1.0-48-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.172-1
(2026-05-15) x86_64 GNU/Linux
(which works) before I reboot to 6.12.88.
Cheers,
Bill.
