I am experiencing data corruption on my AES cryptoloop partition under
recent -mm kernels (including 2.6.1-mm3). I am unsure how long this
problem has existed, and I am unsure if this problem exists in the
mainstream kernel (I can't test it because of an aic7xxx bug in the
mainstream kernel).

Based on this:
http://www.ussg.iu.edu/hypermail/linux/kernel/0312.2/002B.html
I'm guessing that the corruption I am experiencing is because I have a
highmem machine. Its a Dell Precision Workstation 530MT (dual 1.8ghz p4
xeon processors, 1 GB RAM). I am using a reiserfs-formatted AES
cryptoloop on a hard drive partition:
sifried linux # losetup /dev/loop0
/dev/loop0: [000a]:649 (/dev/hda1), encryption aes (type 18)

The problem is easily repeated. Just copy 2 or 3 large (~500 MB) files to
the cryptoloop partition simultaneously, and its almost certain that at
least one of them will end up corrupted on the cryptoloop partition. Just
check with "diff".

Below is some configuration information. Just let me know if anything
else is needed.

thanks,
Jim Faulkner
