Possibly not -- this is a high-risk change!  But it is increasingly
needed for modern hardware.  I figured we should try turning it on
well before the next branch so we can iron out any issues with it on a
variety of real hardware.

We have had this on evbarm GENERIC64 for some time, but obviously
there's a lot of variation between machines and I already had to fix a
few issues with it on x86 last year.

Can you share dmesg for your machine, without PCI_RESOURCE?  Can you
also share `acpidump -dt' output?

And can you describe how it crashes -- does it just give a blank
screen, or does it panic during boot with a message you can
photograph, or what?  Do you by any chance have serial console access
(maybe via Intel AMT)?
