>Description:
Way back in FreeBSD 2.2.5-RELEASE, my gravis ultrasound worked, with the
following exception. Though the sound was excellent, I would get a
constant stream of kernel messages saying "channel X busy". Starting
with some change made to the kernel sources back in 2.2.5-Stable and on,
I can no longer even get sound from the sound card. Attached are the
dmesg, bootup msgs, and kernel configuration. I did as LINT said,
changing the #defines in sound_config.h. I even tried passing the values
for the read and write channels as well as the IRQ into kernel options.

It turns out that the problem is in isa.c and isa.h. If these are replaced
with their counterparts from 2.2.5-RELEASE, then the Gravis UltraSound
works the same as it did before.
