https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261207 Bug ID: 261207 Summary: framework laptop occasionally hangs during suspend to S3 Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: markj@FreeBSD.org My framework laptop can suspend/resume without problems most of the time, though resume takes a long time (~10s, maybe related to some nvme time messages that I see). Suspend occasionally hangs. When this happens, the display stays on, and I see a number of messages of the form hdac0: Unexpected unsolicited response from address 0: 00000000 These messages don't appear when suspend succeeds. After that, some other devices detach, and the system hangs (can't switch to other vtys, no network, etc.). It responds to keyboard input and I can scroll in the terminal but DDB prints output very slowly. All CPUs are idle, but by inserting print statements I can see that the hang occurred somewhere in DEVICE_SUSPEND(root_bus). I haven't been able to reproduce this problem if I manually detach hdac0 before suspending. -- You are receiving this mail because: You are the assignee for the bug.
