| |
On debugging a soundcard driver (the Riptide driver from linuxant, ported by me to 2.6), I seem to have 2 weird bugs that are giving me a headache: Both occur when I try to actually play a file The first: ppos != &file->f_pos If I comment that check out, I get a kernelpanic. If I comment out the schedule_work() to run the bottom half of the IRQ handler, I get the message: irq event 5: bogus return value 19 Followed by: kernel: Disabling IRQ #5 At this point, the first 4K of raw PCM plays, and then /dev/dsp blocks, while the speakers repeat the 4K of data repeatedly until I ctrl+C mplayer. Trying to cat data to /dev/dsp plays first 4K, then cat says /dev/dsp is out of space.
Any ideas?
