Summary:                    crash on snd-powermac initilize
Description: 
I have users reporting a reproducable, on init, crash of our powerpc
distro,
but this happens to only some of the ppc users.

the distro is geexbox, www.geexbox.org

this crash happens also when snd-powermac is compiled as module,
and crashes when module is loaded.

I can't reproduce the bug myself, but I have users who do the tests,
and those users report that debian and ubuntu works great for them.

this bug also happened with linux 2.6.12

I can also confirm this behaviour.  Using 2.6.15 kernel and any
distribution.  I think it's an issue with older iMacs.  My model is:

processor       : 0
cpu             : PPC970FX, altivec supported
clock           : 1800.000000MHz
revision        : 3.0 (pvr 003c 0300)

timebase        : 33333333
machine         : PowerMac8,1
motherboard     : PowerMac8,1 MacRISC4 Power Macintosh
detected as     : 338 (iMac G5)
pmac flags      : 00000000
L2 cache        : 512K unified
pmac-generation : NewWorld

This crashing is definitely not distribution specific, but rather model
specific.

I get the same crash with linux 2.6.16 and gentoo
(gentoo-sources-2.6.16-r1) on an iBook G3

The oops I get:
