Hi Andrew,

I just booted 2.5.33-mm3 and apparently when syslogd was started the
following oops occurred.
Kernel config is attached.

Unable to handle kernel NULL pointer dereference at virtual address 00000000

Then I wanted to send you output of scripts/ver_linux and another oops
occurred with apparently the same cause:
