Ok after thinking about the problem for a bit I realized what happened.
The kiobuf allocation routines switched from using slab allocated memory to vm
memory... (I'm not sure why this was done) but since XFS calls alloc_kiobuf from
thread, and since vmalloc cannot be called from and interrupt thread it was
deadlocking a processor.
I've reverted the kiobuf allocation to using slab allocated memory and things
seem to be running
I need to look at this some more since kiobufs now have buffer_heads allocated
along with the kiobuf
since XFS does not use these bh's it's wasting slab memory.
If anybody really really wants to try 2.4.4 +xfs let me know; I'll generate a
