Stephen,

I tried locking the pages with PG_locked, and guess what? It still
crashes when I use the linux buffer cache routines with getblk(). I
think I am hitting the maximum limit for outstanding IO requests?

The Ooops is in the swapper process again.

Bottom line, Asynch IO is busted in 2.2.15 and does not appear to be
useable unless I limit the number of requests posted at one time to
under 5.
