You most likely can't.  You can't disable ACPI from managing devices
and then expect it to manage PCI interrupts.

As far as your actual panic.  I've looked at the PR's, etc. and there
are few if any details.  For example, what is a "hard crash?"  Does the
machine turn off?  Is it locked up such that it won't respond to pings?
In general, even if it's deadlocked you can break into DDB via a serial
console (trust me, I've seen this far too many times at my day job in
the past few weeks).
