Comment 2 for bug 421244

To clarify the bug a bit:

I cannot boot my kaptop from 9.10 live-cd without using the acpi=off option, else it locks up during the boot process.

The same occurs on an installed system. This is all since the 2.6.31 kernels were introduced.
The same or similar lockups happen with any distro using 2.6.31 kernels I have tried so far via live-cd

Is there a way to help determine whay this is, or to be able to get at the correct logs for this? It happens so early in the boot proccess I cannot get to any terminals or anything useful as far as I can see.
