[Soekris] net 5501 and RHEL5.2

Looks like there is a kernel module called "powernowk8"
The crash is while loading this module.

Get rid of the kernel module in the config.

OR: Maybe the module is part of the initrd RAM disk.
You can make your own with
# mkdinitrd  your_rd   kernel_version

Otfried
