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 which includes 2.6.10-ac10.
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.
Panic messages are similar to:
Unable to handle kernel NULL pointer dereference at virtual address 00000038
printing eip:

*pde = 379c9001
