Kernel panic on x86_64
Last modified: 2008-03-24 11:00:42 EDT
Description of problem:
A x86-64 system panics with recent kernels in current_kernel_time+0x12/0x38.
This is a FOXCONN 6150K8MA-8EKRS motherboard with an AMD Athlon 64 X2 4600+
processor. The machine boots and within a few minutes kernel panics.
We've tried replacing the memory and trying different memory configurations.
The machine doesn't panic while running the Fedora 7 install CD.
Version-Release number of selected component (if applicable):

another panic in swapper (when doing something)
Here's another panic. It seems to have a call trace if it is doing something,
but always crashes in swapper.

yet another panic in swapper
Those oops messages point to some kind of serious hardware problem, like bad
power supply or memory. The system is jumping to addresses in the middle of an
instruction and oopsing on instructions that can't possibly fail the way they do.
Thanks for the comment. It indeed appears to be a hardware fault. It wasn't the
memory, motherboard or power supply. After lots of swapping hardware, it turned
out to be a bad CPU!
I'll close this bug.
