Created attachment 73335 [details] dmesg output Hi, the screen turns to black at the beginning of the boot process. I have to run "setpci -s 00:02.0 F4.B=00" via ssh to see anything. This is similar to bug 668274. Booting with the 2.6 kernel does not show this problem. Best regards Roland Debian bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=680737 uname -a Linux lappi 3.7-trunk-amd64 #1 SMP Debian 3.7.3-1~experimental.1 x86_64 GNU/Linux Debian Wheezy with kernel 3.7.3 (same problem with 3.2.0 but kernel 2.6 works). Machine: eMachines G725

Sorry, bug 668274 is a Debian bug number.
Can you please boot with i915.invert_brigthness=1 and check whether that works better? If so, please attach the output of lspci -nn
Wow, this worked. :) Now I can see all boot messages.

Another gen4 quirk entry for Jani ...
Oops, we actually need lspci -vnn for the quirk entry. Also please attach the output of dmidecode, just in case.

Thanks. Please give me some days time. I compiled my last own kernel 10 years ago. ;-)

I compiled a kernel with the attached patch and it works. :) Thank you so much for your fast help!
