On Saturday I dl'ed and built the CVS kernel, it was running fine until
I logged a few minutes ago and started rebuilding the kernel to add
ipchains, then it locked up. The console would still let me type in the
username but wouldn't bring up the password prompt. Anyway, it seems to
be a problem with nfsd and xfs. Here's the dump, any ideas?
