Hi.

I get random crashes/corruption/ init kills when I use cryptoloop on
this highmem enabled ppc machine.

Applying the loop-* patches at
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test10/2.6.0-test10-mm1/broken-out

seem to fix this problem (at least I did not get any crash due to
cryptoloop in the last 2 days)

Steps to reproduce:

dd if=/dev/zero of=/file bs=1M count=100
losetup -e blowfish /dev/loop0 /file
Password:
mkfs -t ext3 /dev/loop0
mount /dev/loop0 /mnt
cd /mnt
dd if=/dev/zero of=bla

gives you nice unpredictable crashes.
