[Pearpc-users] RE: Darwin Kernel Panic when booting Darwin or OSX on Debian

[<mm...@ru...>]

So it turns out that /proc/cpuinfo reports a clockspeed of 0 Mhz (CPU MHz=

: 0.0000) on my system. This caused PPC to generate some default value wh=
ich
apparently doesn't work well on my system.

I've temporarily hard-coded a clockspeed value into systimer.cc and recom=
piled,
and now ppc works great. 

If anyone else has encountered the problem, another temporary workaround
is to run ppc using "nice" (nice -n2 ppc ppc.conf) -- the lower priority
for the process seems to work better with the default value that ppc is
using.


Now I just need to find out why cpuinfo is broken. If anyone has an idea,=

please let me know.

Thanks,
Marc
