Description Alex Kanavin 2007-07-23 01:37:43 UTC
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): 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

The problem persists with latest kernels 2.6.23-0.61.rc1.git9.fc8 and

Does the GUI work okay once it gets past bootup?

Comment 4 Alex Kanavin 2007-08-06 15:43:21 UTC
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.


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.

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:
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
