Created attachment 330691 [details]
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-
as well.)

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.)

Call trace taken from the panic log in the attachment:

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.

Comment 2 François Cami 2009-02-06 00:47:39 UTC
Closing as NOTABUG since it is a hardware problem, not a bug in Fedora.
