my kernel config for a 22.214.171.124 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 126.96.36.199 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:
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
