Hi all,
as personal preference I compiled kernel with drivers as module as
possible. Recently I found that plugging in USB drives causes kernel
to panic. But it does not happen when booting with GENERIC kernel
which has USB drivers compiled in.
panic screenshot:

back trace:
http://goo.gl/ww4yy6
the kernel is compiled:
FreeBSD 4cbsd 10.0-CURRENT FreeBSD 10.0-CURRENT #1 r253395: Fri Jul 19
15:20:08 CST 2013 jsli@4cbsd:/usr/obj/usr/src/sys/Minimal amd64
the back trace looks like devd and something had timing issues. Any
ideas?
This looks like a CAM/SCSI problem and not directly USB stack problem.
It seems crashed inside the CAM sg driver, that is not part of GENERIC
kernel. Are you using it is some way?
