It's some interrupt event history (positive number for interrupt entry,
negative for exit). It's printed when it sees unexpected interrupts. The
basic problem is a buggy interrupt controller, which generates interrupt
when it shouldn't. The new interrupt code ignores these interrupts. It's
not completely clear why it crashes and without hardware I cannot debug
this. The problem is that this requires some careful adding of prints
and lots of reboots, since too much prints will modify the behaviour and
magically "fix" the problem.
