>Synopsis: Post-upgrade, unhibernating breaks the mouse and unsuspending
>hangs indefinitely.
>Category: system
>Environment:
System : OpenBSD 7.8
Details : OpenBSD 7.8 (GENERIC.MP) #54: Sun Oct 12 12:58:11 MDT 2025
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Prior to OpenBSD 7.8, suspend and hibernate worked perfectly on my
laptop. After upgrading, unhibernating now breaks the mouse,
with the system printing "pms0: device not resuming". Waking from
suspend is also broken, printing what looks like output from
dd(1) indefinitely.
>How-To-Repeat:
Hibernate the Acer Aspire One D255E running OpenBSD 7.8. Power on the
machine. Complete the boot cycle.
Suspend the machine. Wake the machine.
>Fix:
N/A
