>Description:
Locating problems with emu10k driver.  Enabled audio debugging.

Receive the following stacktrace:

panic: kernel diagnostic assertion "(kn->kn_status & KN_QUEUED) == 0" failed: file "/usr/src/sys/kern/kern_event.c", line 1416
knote_enqueue()
knote()
logwakeup()
printf()
audio_write()
audiowrite()
spec_write()
ufsspec_write()
VOP_WRITE()
vn_write()
dofilewrite()
sys_write()
syscall_plain()

>How-To-Repeat:
Either I haven't seen this problem with previous checkouts and it is a recent change, or it just started when I switched from eap(4) to emu10k(4).  I always have audio debugging enabled.
