panic in ffs_blkfree on 4-STABLE

[Michael Nottebrock]

This came out of thin air, I have no idea what caused it and how to reproduce 
it, but I had crash dumps enabled, so here goes... Could this be a sign of a 
hdd going bad?

Backtrace:

IdlePTD at physical address 0x005e9000
initial pcb at physical address 0x004ce4a0
panicstr: ffs_blkfree: bad size
