Subject: panics with 16port Promise Supertrack EX Controller

Hello

I have a problem with a server running 2.6.22rc4. The machine panics
after some days of running fine, the machine inst heavy loaded.

The Controller detects as stex device:

Im not sure where the problem is (controller/lvm/ext3), so if anyone has
an idea, Im happy to try it out...

Thank you
