http://centaur.sch.bme.hu/~oliverp/freebsd/smbfs_panic/DSC01847.JPG

steps to reproduce:
1) mount_smbfs -I server //b...@foo.bar.baz /media/biz
2) generate IO from smb (cp somewate ..)
3) under IO pull down the network cable
4)
  a) wait to panic
  b) umount -f /media/biz, and the system faster panics
