Do a test with ACPI disabled and see if you can reproduce the
problem. It probably will make no difference, but it's worth
checking. If it doesn't affect the outcome, then looking at
more of the panic message would be the next step. Then doing
kernel debugging (instructions in the Handbook, I think; or
maybe the developers handbook).
