I have to take back my other two emails, stating that no corruption
happened with the dm-crypt multi-cpu patch. Today, I encountered
filesystem corruption on one, and a complete hardlock on another machine.
No logfile entries, no m-sysrq, a complete deadlock. Filesystem was
corrupted here too, had to reboot from CD.

The machines with plain 2.6.37-rc4 are up and running...
