Do you know whether your bios already contains the C1 halt disconnect fix? I couldn't find this line in your dmesg: PCI: nForce2 C1 Halt Disconnect fixup Did it occur with earlier kernels? If yes, this is a regression. Try as workaround if athcool off makes your system stable. If yes, you need above fix activated. Cheers, Prakash
