Hi Guys

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

$ uname -a

I recently added emu10kx (, 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
