Hi,

-rc4 does not boot on my MacBook v2.1. Unfortunately, I can not add much 
info on what happens since it's all happening really fast. Last thing I 
can really see is that KMS takes over (?), outputs a few lines which 
look ok, last line being something about ata. Here the boot stops.

Before the switch to KMS I can briefly see something what's probably a 
stacktrace, like < ?blabla >. Only words I could recognize were "?acpi" 
and "mutex".

Config is from make localyesconfig, based on rc3 which is running fine 
(beside the occasional flickering/screen corruption drm/i915 seems to be 
famous for ;) ).

Please excuse layman's terms and let me know if I there is anything I 
can do to produce a helpful error message.

Regards,

Tobias
