sti within interrupt handler

[xvedejas]

The way I'm implementing threading requires that I prematurely exit an interrupt handler. This requires I restore interrupts, but an "sti" doesn't seem to work. I've verified that it does set the IF bit, but the system clock interrupt won't fire, and so my thread switching won't work. Is there a reason why interrupts won't fire even though the IF bit is set?

Do you still send an EOI in the premature exit of the handler?

thanks... I knew I was forgetting something
