I'm not sure that you're allowed to use the task queue that way.
The purpose of the task queue is what they call "software interrupt
handling". When you get a hardware interrupt, you don't want to spend
time blocking other irqs, so you queue the work and unmask interrupts.

At other points in time (return from syscall, interrupt, ctx switch etc), the
task queue is checked and executed. I think calling schedule, when you're
in the task queue, will somehow mark the process ineligible for scheduling.
I'm just guessing here. But what you're trying to do is not what the
task queues are meant for.
