I was able to capture a photo of the hang and this seems to be the most important line: nvme0: Resetting controller due to a timeout and possible hot unplug. When I scan the device after reboot I don't see any errors, but if there is a particular thing I should check via nvmecontrol please let me know. Also, since it mentions possible hot unplug I wonder if this is hardware/firmware related to my system? Anyway, haven't found a repro case yet but it has locked up a few times the past two weeks. -pete -- Pete Wright pete@nomadlogic.org
