>Description:

System panic just fater try to mount msdos filesystem 
(my guess: at first sync after triing to mount)
with message:
panic: sched_sync: fsync failded vp 0xcf4ccc08 tag 19

please note, that mount_msdosfs finished before panic with error
message:

# mount /m/C
msdosfs: /dev/ad0s1: Not a directory
#
