serial console log of the panic
Description of problem:
Since upgrading from Fedora 8 to Fedora 10, my machine has been relatively
unstable, with frequent kernel crashes and lockups. I have captured the
latest one on a serial console in the hopes that maybe the problems can
be identified and resolved.
Some earlier crashes that I can find logs for appear to be roughly the
Version-Release number of selected component (if applicable):
(for this crash; I have had crashes in kernel-126.96.36.199-159.fc10.x86_64
Asus M2N4-SLI motherboard, Athlon X2 4600+, 6 GB of memory, ATI Radeon
X300 PCIE video card. I believe that I've had crashes both with and
without 'nomodeset' as a kernel command line parameter, but this crash
occurred with 'nomodeset'.
(I use 'nomodeset' because if I do not, X eventually slows down and
becomes achingly slow until the system is rebooted; quitting and
restarting the X server makes no difference.)

(I am inlining this bit for easier searching in Bugzilla.)
Your system almost certainly has a hardware problem, probably bad memory but it could also be overheating or have a defective CPU.
It is trying to restore the stack pointer to an illegal address: feff88019f0dffa8
This is exactly one bit different from a valid address, indicating that a bit was flipped.
Closing as NOTABUG since it is a hardware problem, not a bug in Fedora.
