Kernel Oops in Etch 40r3

[digbyt@skaro.afraid.org]

I have a system very recently installed from the Etch 40r3 netboot CD which
has just given me an oops in kswapd0:

System can still be pinged, but ssh doesn't work. I need to get it rebooted
before I can include detailed installation data.

The problem may be related to an overnight scp of a large (~GB) file
which was 97% complete when the system froze up.

Does this look like a known problem? If so, is there a fix? If not, pls let
me know how best to followup.

Thanks,
