When this reproduces, can you run 'procstat -kka | egrep "bsnmpd|devd"' and paste the output in this bug? Possibly run it a couple times and paste each output. (In reply to Conrad Meyer from comment #1) Ok.

I am getting this on vultr.com/netcup.de seems to be happening only on "QEMU" since in AWS or GCE I don't see the error: Processing event '!system=CAM subsystem=periph type=error device=cd0 serial="QM00003" cam_status="0xcc" scsi_status=2 scsi_sense="70 02 3a 00" CDB="00 00 00 00 00 00 " Just in case I am using this kerne: https://github.com/fabrik-red/images/blob/master/fabrik.kernel This should be fixed by now in stable branches. *** This bug has been marked as a duplicate of bug 215471 *** Isn't the bug actually addressed in PR 209368? The currently linked bug is also a duplicate of PR 209368 (but still open for some reason, maybe it can be closed). (In reply to Conrad Meyer from comment #7) Yes, all three of them seem to describe same problem. Cool. *** This bug has been marked as a duplicate of bug 209368 *** |
