Subject: 3.6-rc7 boot crash + bisection
Hi,
I think I've found a regression, which causes an early boot crash, I
appended the kernel output via jpg file, since I do not have a serial
console or sth.
after bisection, it boils down to this commit:
9dcd61303af862c279df86aa97fde7ce371be774 is the first bad commit
