Hello, thank you for helping me! I'm sorry that I was so slow. My
loglevel was wrong so I started messing with netconsole.

I tested this with 3.4.4 kernel. I realized that your module seems to
be from git version of kernel, it compiled without errors tho. I can
try compile git kernel if that's better!

I only have root= and ro
[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.4.4 root=/dev/... ro

But I forgot to mention these lines
[    6.634492] ACPI Warning: 0x000000000000f040-0x000000000000f05f

(20120320/utaddress-251)
[    6.634496] ACPI: If an ACPI driver is available for this device,
you should use it instead of the native driver

and that i tried booting with something like "noacpi acpi=off", but it
still froze.

You are correct! No freeze and the values looks kinda sane.

I only see these lines:

[  265.410655] it87: Beeping is supported
