my kernel config for a vanilla kernel


My 2.6.38 kernel fails to boot when using the nouveau driver. See these pictures of the kernel output while booting:


I made 3 pictures because I wanted to show the effect of the "shifted" text in the fullscreen picture where you can barely read the text. The other two pictures show the text.

I am running gentoo linux and I used kernel 2.6.37 for quite a while with no problems but was not able to produce a working 2.6.38 kernel. I have tried the gentoo-sources-2.6.38-r1 and also a vanilla kernel and the behaviour is the same for both. I have attached my kernel config.

Looks like I found the culprit:

In a desperate attempt I have deactivated the boot logo display in my kernel and now it boots with no problems.

Please tell me if and how I can help debugging this. For the moment I can perfectly live without the boot logo but I would like to contribute something to nouveau development if I can.

This is probably the same bug which was reported recently:
Comment 3 Marcin Slusarz 2011-04-22 07:37:10 UTC
Yes, it's the same bug and it's fixed by commit a18d89ca026140eb8ac4459bf70a01c571dd9a32 "drm/nouveau: fix
notifier memory corruption bug" (after 2.6.39-rc4).

It will soon go to 2.6.38-stable.

If you are impatient, you can apply it manually from: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=a18d89ca026140eb8ac4459bf70a01c571dd9a32
