It seems really unlikely that the kernel is causing this. Especially if
the CPU fans shut off, how would the kernel cause this to happen?

Might be unrelated, or caused by the same root cause.

Are you certain? Seems suspicious.

It may some kind of hardware issue that 2.6 is triggering and 2.4 did not.

Can you post the full dmesg please?
