I tried adding "irqpoll" to my kernel run line (grub.cfg).
After rebooting, I noticed that right after "Disabling IRQ16", I got an
"irq18 nobody cares (try booting with irqpoll option)". Then it ran for
a bit and OH NO "Kernel panic: CPU 4 PID 0 comm: swapper/4 tainted" and
my keyboard's light started flashing.
The kernel panic reproduced twice before I removed "irqpoll" and I was
able to boot again.
Did this tell us something?
