[mythtv-users] AMD Phenom Lockups

Sat Mar 21 01:09:46 UTC 2009

OK, this is marginally on topic - my backend has an AMD Phenom and it's 
locking up somewhat randomly.

I've finally caught the culprit in the log files:

Mar 20 13:32:53 selene kernel: [67211.265120] Fixing recursive fault but 
reboot is needed!

A few more of these and the system hard-locks.

So it looks like the freq governor.  Anyone know of any issues with 
phenom cpu governors?  Which are safe to use and which aren't?

Thanks,
