Even when I mount a valid root over NFS, the kernel always says:
Warning: unable to open an initial console.
It seems like we'd need to enable polling (NAPI?) for the sunHME in
order to use netconsole here, or fix the native console. Any suggestions
would be welcomed.
Here is the full log for 2.6.20-rc6, from OBP to dmesg, on a rather
small domain:
