>Release:        2.2.2
>Environment:
Can't, I've since upgraded to 3.0-SNAP-Aug08 (whatever)
>Description:

I changed from a ASUS T2P4 motherboard with 430HX chipset to an
ASUS TX97 motherboard with a 430TX chipset... System locks up 
on restart while accessing my IDE disks. This behaviour only occurs
when the AUTO_EOI_1, AUTO_EOI_2 kernel options are used.
>How-To-Repeat:

On a system with an ASUS TX97 motherboard, build a kernel with these
options and reboot :) .. Should lock up during filesystem checking/
mounting.
>Fix:

Build a kernel without the AUTO_EOI_X options.
