So the soft lockups just seem to be more evidence to my theory. If I just would know better all this timer and tickless stuff. What seems to happen is that your machine enters idle and probably should be awoken by a timer tick. Which somehow doesn't happen. Interrupts are enabled to anything that causes an interrupt will also awake the CPU.
Upstream had one more change (to increase the minimum timer delay if the current minimum can't be programmed) which I included and put to -3.3smb4.
Any chance you could get a timer dump (alt+print+q) during a pause, or at least cat /proc/timer_list after boot?
