Hello,
On a custom SC1100-based board with 16M diskonchip using 2.6.11.2.
I have two ext2 partitions on the diskonchip, nftla1 and nftla2.
I use lilo to boot a kernel and initrd from nftla1, then mount nftla2
via startup scripts for config settings, but after ~15 minutes basically
idle, this happened:
Unable to handle kernel NULL pointer dereference at virtual address 00000001
printing eip:
c0238848
*pde = 00000000

I notice it says my kernel is tainted; that's because of the wd1100 watchdog
driver required for reboot functionality on the geode SC1100. I will try again
without loading the watchdog and then, with the latest mtd source, and if
someone says it's worthwhile, I 'll try 2.6.12-rc1 and latest mtd.
Want anything else while I'm compiling?
Thanks.
