Re: Audigy problems.

:Up to two weeks ago, that version of the snd_emu10k1.ko driver would
:load under DF and run without any (noticable) problems.  I updated my
:copy of the source tree yesterday, and rebuilt world and the kernel.
:Unfortunately, it seems that audigy driver no longer works, but I have
:no idea how to track down the source of the problem.  This is the kernel
:panic andtrace:

    Ok, this is a real simple fix.  Your driver is calling malloc() without
    either the M_WAITOK or M_NOWAIT flags.  It must call malloc() with one
    or the other.  If it is not using either flag then add M_WAITOK to it.

    Yes, there are people that have been informally working on backporting 
    some of the drivers from 5.x.  In fact, I was under the impression that
    the a patch is in the works for the Audigy:

:From: Emiel Kollof <coolvibe@xxxxxxxxxxxxxxxx>
:This patch, mostly obtained from FreeBSD CURRENT, allows many ac97
:mixers and cards to work properly again. It works for me at least. :)

:Please test and review, (and hopefully) commit.

    Which I believe Jeroen committed:

:Applied, please don't strip $DragonFly$ next time.
:Thanks!
