udev-095 here.

Some slightly odd messages in dmesg.  Overall this -mm boots and runs and seems 
to be reasonably good (the last -mm didn't boot for me).

1. NMI message - I too, am dazed and confused about this one:

Uhhuh. NMI received for unknown reason 3c.
Do you have a strange power saving mode enabled?
Dazed and confused, but trying to continue

It's a desktop PC/server, no strange power saving mode going on here.  Unsure 
who looks after this or why it would occur.


2. Think this is ok, but still - timeouts, frozen - all words that suggest 
suboptimal things have gone on:

The device on ata1 is the DVD-RW Atapi.

All devices seem to be detected and work, so it may be just cosmetic.  Alan?
