Synopsis: 6.7-stable USB3 panic: assertwaitok: non-zero mutex count: 1
Category: kernel
Environment:
System : OpenBSD 6.7
Details : OpenBSD 6.7 (GENERIC.MP) #2: Thu Jun 4 09:55:08 MDT 2020
r...@syspatch-67-amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
Description:
After ~1-2 days the server crashes. The USB3 network adapters (cdce)
appear to be involved as this does not happen on a USB2-only backup server
running 6.7-stable. This also did not happen with 6.6-stable. I saw similar
crash reports on bugs@ recently. Just sending this as it may contain additional
information.

rebooting...
How-To-Repeat:
Just let the server run normally 1-2 days with moderate traffic on any
of the USB3 network interfaces.
Fix:
Use 6.6-stable or 6.7-stable on USB2-only hardware.
