Hello, I see in the source (linux ver 3.3) that wake_up_interruptible function doesn't sleep so I used in it an ISR but I'm getting 'BUG:scheduling while atomic' message. (I'm not sure it's coming from this) I'm looking for the exact cause but Is there any caveat when using wake_up_interruptible() in an ISR? (I found some drivers use it in ISR, some use it in work_struct) I also read in http://www.slideshare.net/rampalliraj/tasklet-vs-work-queues?from_action=save that tasklet is not allowed to sleep but work is. (because tasklet is not in process context, but in bottom-half) I don't know if I have to move the wake_up_interruptible function to tasklet or work(queue) or even it matters to the current problem. Any help would be greatly appreciated.
