This is similar to a message send to linux-kernel recently.
I have a Dell PE2650, Dual Xeon, 1G memory and several software raid1
partitions, ext3. Main duties include NFS, DHCP and samba. A Fedora
kernel 2.6.10-1.747_FC3smp. This has 2.6.10-ac10 which includes the
recent "bio clone memory corruption" patch.
This system panics frequently, between several hours to several days. It
does not seem to be related to load. Hardware and memory tests indicate
a good system.
A sample panic message:
Unable to handle kernel NULL pointer dereference at virtual address 00000038
printing eip:

*pde = 379c9001
