Bug#496334: mdadm: --assemble -f also fails in a raid5 setup

Package: mdadm
Version: 2.6.7-3
Followup-For: Bug #496334

This also happens for a RAID 5 setup. Specifically,
I was working on a degraded RAID5 (four out of five
disks present) when a bus error or similar stopped
md_mod from talking to one of the disks, which was
then marked faulty.

After a reboot I tried to tell mdadm that all was
well again, but it kept segfaulting.
Downgrading to lenny's mdadm (2.5.6-9) allowed me to
re-sync the metadata and use the array again normally.

No filesystems were harmed in the production of this
bugreport.

FWIW, the array has version 00.90 metadata.

Ciao,
  Philipp
