Well heres the story, I was bored today so I hacked up a little proggie to
set the keyboard leds according to music volume(read from /dev/dsp with cd
playing.) Anyway after attempting to set the kbd leds 11000 times per
second (:)) I start getting:
Sound: DMA (input) timed out - IRQ/DRQ config error?
Now sound it dead(with the same error) till next reboot. Fun fun!
I'm blaming this on interrupts becuase in my snooping I discovered:
extern inline void set_leds(void)
{
mark_bh(KEYBOARD_BH);
}
in kbd_kern.h...
System stats and the prog I was using attached after sig - Happy
bugfixing!
