FreeBSD vulcan 5.3-STABLE FreeBSD 5.3-STABLE #15: Wed Oct 27 17:31:14 CEST 2004     root@:/mnt/AC26400R/usr.obj/usr/src/sys/VULCAN  i386
I get a panic detaching my USB mass storage during final sync,
without previously unmounting it.

I don't know if this is a real problem (since I did not unmount the
USB mass storage), but it leaves my root filesystem unclean.

That's my logs:

(umass detaching logs...)
(...) 1 1 0 0 0 done
No buffers busy after final sync
(da1:umass-sim0:0:0:0): Synchronize cache failed, status == 0x39, scsi status == 0x0
(da1:umass-sim0:0:0:0): removing device entry
panic: vinvalbuf: dirty bufs
Uptime: 1h23m45s

Attach an USB mass storage, mount it, and then reboot or shutdown,
when final syncing detach umass.
