After resuming from suspend with 12.1-RELEASE, all processes accessing disk hang for 30 seconds, rendering the system frozen from user's perspective. After this, dmesg has: nvme0: Resetting controller due to a timeout. nvme0: resetting controller nvme0: aborting outstanding i/o (... many repeats) nvme0: aborting outstanding i/o nvme0: async event occurred (type 0x0, info 0x00, page 0x01)
This was fixed on CURRENT and MFC-ed to 12-STABLE. See details on bug #211713 You can also try to decrease timeout: sysctl dev.nvme.0.timeout_period=10
per comments, this issue has been fixed in the supported releases.
As of comment #1, it was not fixed; I have had to use the workaround instead (on 12.2-RELEASE and newer). I haven't tried it since switching from Toshiba to Samsung nvme, but with same notebook and same buggy vendor ACPI. Anyway, this is not something I care to spend further time investigating, as the notebook has mostly become a desktop machine, and it doesn't seem to affect anyone else anymore.
(In reply to Theron Tarigo from comment #3) OK. If you upgrade to 13.0 or newer and still see this issue, please reopen this bug or at least drop a comment here. I believe everything should be in at least stable/13 to keep this from happening. stable/12 is older and may still suffer from this problem.
