Hi Guys

I have to just say first, I'm pretty new to this, please be patient :)


Firstly:
$ uname -a
FreeBSD ************** 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov 3
09:36:13 UTC 2005 root@xxxxxxxxxxxxxxx:/usr/obj/usr/src/sys/GENERIC
i386

I recently added emu10kx (
http://www.freebsd.org/cgi/url.cgi?ports/audio/emu10kx/pkg-descr), but when
I run kldload snd_emu10kx.ko the Kernel panics.

As follows:

----
Kernel trap 12 with interrupts disabled
Fatal trap 12 : Page fault while in Kernel mode

fault virtual address =0x74
fault code = Supervisor read,
page not present
instruction pointer = 0x20: 0xc0 657d4d
stack pointer = 0x28: 0xef 71894c
frame pointer = 0x28: 0xef 718950
Code segment =Base 0x0, limit
0xfffff, type 0x1b
= DPL 0, pres
1, def321, gran 1
Processor eflags = Resume, IOPL =0
Current process = 686 (kldload)
Trap number =12
----


I can't find anyone with the same issue on google, so I guess the problem
goes deeper that the sound card driver.


Can anyone suggest where to start looking?

Thanks in advance

1. Tell about this to the port maintainer of /usr/ports/audio/emu10kx ?
2. Try to use snd_emu10k1.ko from base system ?

Sincerely,
Tofik Suleymanov
