Bug#418750: linux-image-2.6.20-1-powerpc: kernel fails to boot on mac mini G4

[Marko Kaiser <Marko.Kaiser@t-online.de>]

Package: linux-image-2.6.20-1-powerpc
Version: 2.6.20-1
Severity: important

Hi,

if I boot my mac mini g4 with 2.6.20-1-powerpc bootup process hangs with 
PMU not responding (!ack) after modprobing eeprom and before 
initialising the devmapper. I have no clue what's going on.
My old kernel does boot very well instead.
Let me know what I can do to help you to find the error.

Regards,
Marko
