Having glanced across another thread that mentions IRQ accounting

with the stuff that Marc's trying to clean up.
Thanks Robin. I've applied Marc's "[PATCH v2 00/17] arm/arm64: Turning
IPIs into normal interrupts" series and the LS1028A I'm debugging hangs
in absolutely the same way.
I'm not too surprised by that, wrt accounting this mostly changes where the
stores go to and barely shuffles when they happen (slightly earlier on the
IPI handling path).
FWIW I've had 'stress-ng --hrtimers 1' running on my Juno and eMAG for ~15
minutes and haven't had a splat yet.
