Bug#415239: linux-image-2.6.18-4-amd64: general protection fault from powernow-k8
Package: linux-image-2.6.18-4-amd64
Version: 2.6.18.dfsg.1-11
Severity: normal
I'm running AMD64 x2 4200 (ie dual-core). I've only just upgraded from
2.6.17, which was working fine.
Soon after boot I get a general protection fault;

The system seems to keep running though I haven't stressed it to see if it
changes frequency succesfully.
Some time later I've also had the following (3 times); don't know if it's
related, but I wasn't hotplugging anything at the time:
