Subject2.6.0-test1 issues, ACPI, USB, ALSA
Here are the problems I've found thusfar:

1. must boot with either acpi=off or pci=noacpi. If this isn't done,
half of things don't work right (eth0, USB mouse, etc) and when trying
to use such devices, I get a message to the effect of IRQ NN disabled

2. randomly some IRQs stop being delivered or something. I notice it
first in X when my USB mouse stops working. The PS/2 glidepoint mouse
keeps working fine. Most everything else on this IRQ (ohci-hcd, eth0)
all stop working -- sym53c8xx keeps working.

3. only 1/2 of my USB ports work. I have 6 ports, ports 1, 2, and 5
don't work.

4. if I try to use my i8x0 onboard sound (ALSA), I immediately lose
mouse/eth0/etc as above and I get a flurry of messages as will be described.


Now for the texts.

The other ports are respectively similar.

I'll put the lspci and dmesg and .config up on the web
(http://stuph.org/2.6.0-test1-issues) due to the size.
