Re: PowerPC install stuck at dmesg

I had similar issues with hanging on boot about a month ago with 
powerpc and I believe that it ended up being a corrupted boot ram 
image.  Would drop into a limited shell when it tried to switch to 
mounting the root file systems and visually "hang".  Sounds somewhat 
similar, but I cant tell from your description if its exactly the 
issue.  In my case I wasn't able to switch to any other console, but I 
could type around int he initramfs shell still after the boot "hang".

The mdadm driver (not used for booting on my machine) was corrupting 
the initram regeneration.  Removing and supressing the reinstalltion of 
the mdadm script part of initramfs regeneration allowed a clean 
initramfs to be built which booted fine.

Might be one of these bugs or another similar 

My system did not boot even though the root filesystem was not on an 
raid volume.

This really may not be your issue, but the symptoms go in the same 
direction, so I though I would bring it up.
