2.6.11-rc5-mm1: reiser4 panic

[Alexander Gran]

Hi,

after my external USB hdd disconnected itself reiser4 paniced. I dont think a 
journalingfs should panic if its device fails..
Log:
scsi2 (0:0): rejecting I/O to dead device
reiser4[ktxnmgrd:dm-0:t(25324)]: reiser4_handle_error 
(fs/reiser4/vfs_ops.c:1315)[foobar-42]:
reiser4 panicked cowardly: Filesystem error occured
