Description Andrey 2009-12-22 16:50:01 UTC 
On USB flashdrive there is a file with a long name.

# mount_msdofs -L ru_RU.UTF-8 /dev/da4s1 /mnt/flash
# ls /mnt/flash
msdofs: file name length 266 to large
msdofs: non-decreasing id: id 0, last id 2
msdofs: file name length 266 to large
msdofs: non-decreasing id: id 0, last id 2
panic: stack overflow detected; backtrace may be corrupted
cpuid = 0

After file removal it is mounted without problems.

How-To-Repeat: # mount_msdofs -L ru_RU.UTF-8 /dev/da4s1 /mnt/flash
# ls /mnt/flash

Fixed by using the 8.3 name if the converted long name is too long.
