bio_put oopses in 2.6.3-mm3 when resyncing reiserfs/raid1

[Jurriaan]

I got this in 2.6.3-mm3 when rsyncing my reiserfs on raid1 system.
The taint is vmware (with the latest vmware-any-any updates) but X
hadn't been started, let alone vmware. It happened multiple times,
until I rebooted 2.6.3-mm1 and all was fine again. I don't see any
patches in 2.6.3-mm4 that would solve this, and I couldn't find any
similar reports on lkml.

So here goes:

Okay...how did Aragorn turn a Broken Sword into Anarion?  The book
mentions "forging".  Nice euphemism for "hacking"; he obviously went
to the Forge of Hex Editing.  I think he took cheating lessons from
Gandalf.
