Re: oops on e4k5

[David Miller]

The OOPS is severely truncated where the most important
information would normally appear.  Please reproduce with
the following patch applied.

It might also help if you turn off CONFIG_PROM_CONSOLE.
The zilog serial driver should drive your console just fine,
and your logs show it does register properly.

Also, what kind of cpus are in this machine?  (/proc/cpuinfo
output is sufficient)

Thanks.
