Sort of.  Weirdly.

The system boots, and I get what appears to be a working eth0.  This
machine mounts some NFS filesystems, though, and as soon as I try to do
that, everything locks up.  I've come to expect NFS to be slow, but
that exceeds my expectations somewhat.

Other things seem to work, so, maybe, the NFS thing is a totally
different problem, don't know.

Nothing useful in the syslog, of course.  Here's dmesg, in case that
helps.  I have to run to a meeting, can't really look any deeper at the
moment.

Thanks,

jon
