thanks for the detailed report and bisection test! The above hang
strongly implicates some sort of high-res timers, dynticks or
clocksource problem. Most likely timer interrupts do not come as
expected, and the above place is one of the first spots where the kernel
waits for a (short) timeout - so you see it hang indefinitely.
Besides the options Thomas suggested, you could also try
clocksource=pm_timer?
