Subject: 2.6.0-test1 panic output in bio_end_io_pagebuf

The system was running X and under pretty heavy load (basically, a 
fork bomb). I had to copy the panic off the screen so there may be
a couple of typos. I still have the build tree here, but the critical
files are at http://csgsoft.doc.ic.ac.uk/2.6.0-test1. If anyone has
any questions please mail me directly.
