You should be able to solve this by not including APIC (note: not the same as ACPI) in the kernel. This can be done during compilation of a kernel or by using the argument "noapic" during boot, though I have had much more success with the do-not-compile-APIC option.

This sounds like a suspend/resume (to and from RAM) problem. I've been dealing a lot with with suspend/resume problems... It can be frustrating :) In my experience with an R40, ACPI is not there yet if you want to suspend and resume. I use APM, it works much better.

Does the same thing happen when you suspend (or go to bed) from a shell?  In regards to APM, I saw on the net that there is a difference between suspending from a shell vs. suspending using Fn+F4 (or closing the lid). It had to do with the order of suspend commands (who came first, BIOS or kernel). The recommendation was to stick to shell suspending. Perhaps the same thing is true for ACPI.

Personally, I disabled suspend-when-closing-lid in BIOS.

I believe Fn+F4 is the combination to tell BIOS to suspend? There may be some conflict there. I don't have Bluetooth though, so I'm not sure.
