OK, thanks. There have been a few serial driver changes recently, but
there's also a tremendous ACPI patch in -mm. I'm wondering about those
ACPI error messages:

Does the above happen on 2.6.13-rc3 or 2.6.13-rc4?

Well it did claim to find an 8250 controller.

If you have time, it would be useful if you could obtain the 2.6.13-rc3 dmesg
output and do

diff -u dmesg-2.6.13-rc3 dmesg-2.6.13-rc3-mm3

and send it, thanks.
