- ia64 doesn't compile due to improvements in acpi.  I already fixed a huge
  string of build errors due to this and it's someone else's turn.

- For some reason Greg has resurrected the patches which detect whether
  you're using old versions of udev and if so, punish you for it.

  If weird stuff happens, try upgrading udev.

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?
