AAAG

9-current as of r199418, vlc 1.0.3_1, with data on an msdosfs partition.
>Description:
When I try to access multimedia files on an msdosfs partition the kernel
panics. Accessing the same files on the command line, with another client
(mplayer), or from a UFS partition does not cause any problems.
Panic is as follows:
(kgdb) #0 doadump () at pcpu.h:246
#1 0xc05f5a2f in boot (howto=260)
at /usr/local/src/sys/kern/kern_shutdown.c:416
#2 0xc05f5d12 in panic (fmt=Variable "fmt" is not available.
) at /usr/local/src/sys/kern/kern_shutdown.c:579
