On my test box, I'd been playing with xfs, then
umounted, rmmoded and insmoded the modules. When
pagebuf was insmoded, this kernel BUG() was tripped.

I'll see if I can get some more info on this one.

==========================
ADDITIONAL INFORMATION (REOPEN)
From: dxm@engr (BugWorks)

==========================

With XFS (and pagebuf) as modules, and after a failed mount,
warning messages are generated on module unload and a kernel
BUG() is triggered on reload of the module.

This is repeatable - I just couldn't rember how I did it
earlier.
