Subject: stopping a process during a timer interrupt

On a timer interrupt, I tried to stop the current process by changing
it's run state to TASK_STOPPED via set_current_state(TASK_STOPPED).
However, this results in a system hang.

I can't find a way to stop the current process during an interrupt
context. Does such code exist in the kernel? If not, how does one go
about implementing it from within a kernel module.

Thanks.
Kay Tiong
