SubjectRe: 2.6.16-rc[1-5]: soft lockups on Athlon64 X2

Here it is. As an explanation of the profile's scope, I have also
sent the shell script which reproduces the problem on my machine.

The script however is not 100% reliable; sometimes, the lockup just
won't occur. Sounds like a timing problem to me.

btw. my other partitions are also reiserfs (but not encrypted).
