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:

Why the dependence on i2c-powermac is not explicit?

Johannes Berg - 04-03-06 10:56
----------------------------------------------------------------------
Because it calls it implicitly via the i2c layer so the dependency cannot
be determined at link time.
The problem is just that snd-powermac detects a chip even if the i2c stuff
isn't there -- it shouldn't, it should do a proper i2c driver instead.
Note that there's some effort I am currently doing on writing a new sound
driver called snd-aoa (google) that does this correctly and will likely
deprecate snd-powermac in the future so I recommend not investing too much
time and brainpower into fixing it.

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

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
