Right, I suppose you were referring to the DMA buffer still under control of the hardware. I'll add a timer in that case. BTW, what guarantees that the dequeue function can't called after the ISR is invoked but before the schedule_lock is taken? If that can happen then wouldn't it free the DMA buffer that's in use as well? -- Debian GNU/Linux 3.0 is out!
