Dear list!
There seem to be some problems with P8400 based laptops and ACPI when
using 64 Bit kernels.
See for example:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/272530
I have such a laptop. What can I do to help find and possibly fix the
problem?
Regards,
Torsten

Would be useful to narrow down what causes the problem.. It's reported
that either mem=4096M or acpi=off is required. It would be useful to
build a kernel that has some of the ACPI features (CPU frequency
scaling, etc.) disabled and see if you can find out which part is
causing the problem.
This does smell quite possibly like some kind of BIOS or platform bug,
though. Obviously Vista 32-bit works, but who knows about 64-bit..
