I use an radeon HD 4670 graphic card and can't boot with the 3.3-rc3 kernel, while it works fine with 3.2 (3.3-rc1 and 2 not tested).
The system just hangs and shows me the attached screen. MagicSysRQ not working.
Can't attach the image as it's to big, so: http://img269.imageshack.us/img269/778/dsc01960ko.jpg
Future testing showed that the error is presented since 3.3-rc1
Still presented in 3.3-r4.
Can you bisect?
I'm not that expert, but I think bisect has something to do with git?
I'll try to figure it out for myself, but it would be great if you could give me step-by-step instructions what to do.
Okay, I found a description here: http://kerneltrap.org/node/11753 and hope that cloning 2.6 is right.
Also, as a sidenode: The cursor (down left side of the screen) blinks for a few seconds while the system still doesn't react to anything and shows the yellow lines before the screen freezes, too.
I started with
git bisect good v3.2
git bisect bad v3.3-rc1
and every builded kernel had the issue (more or less, at some point near the end the screen just goes to standby instead of freezing, but every time before freezing/going to standby it showed the yellow lines)
So at the end I got this:
a858393b0ce5c330bda466e5ae3a658ca98588ae is the first bad commit

But how can a bluetooth change cause that? :(
Okay, I tracked this down more and was able to boot a 3.3-rc4 kernel. The problem was that radeon and uvesa was compiled into the kernel.
Ok, this bug can be closed then.
