This wasn't a power cycle.  It was a software-initiated reboot.  It
does appear to hang in the firmware somewhere.  Do we expect the pci
training issue to occur in this case ?

There is some heisenbug where qemu crashes with very low probability.
(I forget whether only on arm or on x86 too).  This has been around
for a little while.  I doubt this particular failure will be
reproducible.
