Unfortunately, I still experience the same hang on integrator with this
revised patch series. Given the turnaround time for testing this, I don't
think this should block the series, but I would like to get to the bottom of
it if possible.

I tried annotating the PCI code (including fault handlers) and the VGA
console code but I couldn't find the culprit. I suppose the next step is
JTAG, but that requires steal^Wborrowing some hardware from work.
