kernel 2.6.22 corrupts console output during boot (Apple Powerbook 12", GeForce FX 5200)
Last modified: 2007-12-07 20:11:26 EST
Description of problem: on my powerbook 12" with GeForce FX 5200 during the boot sequence the console output is corrupted so that it's totally unreadable. Using video=ofonly option fixes the problem. Also, it only happens when using an external display. Version-Release number of selected component (if applicable): 2.6.22.1 kernel update 2.6.21 worked fine How reproducible: every time during boot Steps to Reproduce: 1. Start booting the system 2. Watch the output
Created attachment 159756 [details] a photo of the screen with corrupted output
The problem persists with latest kernels 2.6.23-0.61.rc1.git9.fc8 and 2.6.22.1-41.fc7
Does the GUI work okay once it gets past bootup?
Yes, it works well. I think there are problems if you switch from GUI to the console and back, but if you stay in the GUI, it works fine.
Hello Alex, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. Cheers Chris
Hi Chris, I've taken the issue to the kernel framebuffer maintainer, and we have identified the patch that caused the regression. He has just produced another patch to reverse the original one: http://sourceforge.net/mailarchive/forum.php?thread_name=46EB2077.2060004%40gmail.com&forum_name=linux-fbdev-devel so when it makes its way to the kernel, and from there to Fedora repo, the problem should be gone. I'll be happy to close the bug then :)
2.6.24 kernels have the fix included - the problem is fixed in rawhide
