Public bug reported:

When trying to boot using kernel 3.2.x kernel the screen just goes blank and 
harddisk IO stops.
Removing the quiet and splash options in combination with nomodeset seems to 
reveal
that the booting stops due to an error in setting the firewire's power levels 
(see attachment)
Kernel 3.0.x work fine.

ps
