Can you please try to boot and change the cpufreq governor to
performance and back and see if that works?

I cannot change to governor with 9be4fd2c7723a305.

After running 'cat performance >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor'
the system hangs silently.

So this means that irq_work doesn't really work on your system at all.
It looks like queuing up an irq_work sort of works (because the
IRQ_WORK_BUSY), but then the queue is never processed.

I wanted to say "because the IRQ_WORK_BUSY flag is set", sorry.
