Hi All.
I`ve got a problem which cannot resolve. I`m using schedule_work in my interrupt handler to do the needed work out of the irq. I made INIT_WORK in probe() of the driver. When the interrupt occure-nothing happens. If I use it anywhere else - work goes. Work function is never reached in irq, my printk shows nothing.
I`ve read about work_ in LDD3 and elsewhere, I`ve tried clearing pending bit. If I clear it I got a BUG in a workqueue.h in queue_work_on.
So my question is what are the possible reasons for work to be pending always?
Thank you!

Sergey,
This is a general linux kernel programming issue, not related to blackfin. You may ask somewhere else.

Thank you, Yi.
I`ve found some similarities with errors some people find in gcc-4.3, I`ll try to upgrade. If I will be lucky-I`ll tell.
Greets,
