Thank you for identifying this. I have been having perfect results iwth
the systems I have running cryptoloop, but they are both small. Now I
not only know why I don't have problems, I have a way to prevent
problems.

Hopefully this will get into 2.6.0-final, since it fixes a hard fail case.

| 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.
