Lee, can you cause this problem with PREEMPT_DESKTOP with softirq as

I am just posting this for Pieter - all followups should be directed to
him. (I don't even have the hardware to reproduce this)

IIRC the problem could only be reproduced with PREEMPT_RT. Pieter, can

It can only be reproduced with PREEMPT_RT. And the test kernel is configured with irq threading, I haven't tried it without irq threading.
