Subject: Re: Linux 2.6.31-rc7

Hi,

I am far away from being a coder or a kernel geek, so bear with me if I 
can not provide all information on first try.

Unlike rc6, this rc (rc7) does not boot correctly on my Macbook 2.1. I 
am using amd64 kernel-debs provided by Ubuntu on 
http://kernel.ubuntu.com/~kernel-ppa/mainline/.

During boot with rc7, I can unlock my encrypted volumes just fine. After 
that, boot continues till suddenly screen goes black. I can not tell if 
the whole thing hangs or just the screen dies, but I can tell that the 
only way to get out of that limbo seems to be the power button. Again, 
everything seems to work flawless with rc6 Ubuntu deb.

Assuming that dmesg output of rc6 and rc7 should look kinda similar, I 
tried to narrow the problem down to the following part in the output of rc6:

(complete dmesg attached)

I think the problem must be somewhere in here because when booting rc7 
(in rescue mode), the last thing I can see before all goes black is the 
frequency table shown in the first lines of the quoted section. (Also, 
there are scary-looking errors near the end ;) )


/proc/version/
Linux version 2.6.31-020631rc6-generic (root@...c) (gcc version 4.2.3 
(Ubuntu 4.2.3-2ubuntu7)) #020631rc6 SMP Fri Aug 14 09:04:48 UTC 2009


Please let me know what further info is needed.

Regards,

Tobias
