As root.

Not well versed with interpreting kdump, though probably following trace
lines seem to be of interest to me:

   189      1 mount_cd9660 0.000001835 CALL
__mount50(0x8048e74,0xbfbfe3f8,1,0xbfbfebf8,0x74)
   189      1 mount_cd9660 0.000001209 NAMI  "/mnt/tmp"
   189      1 mount_cd9660 0.000011005 NAMI  "/dev/vnd0a"
   189      1 mount_cd9660 0.017054948 RET   __mount50 -1 errno 22 Invalid
argument

kdump -R | grep EINVAL shows nothing.

Let me know what else shall I look for in the trace.
