Hi Ben,
3.7-rc1 messed up the screen on my MacBookAir3,1 (nv50, 0xaf) pretty
badly. Not surprisingly,
commit 3863c9bc887e9638a9d905d55f6038641ece78d6
Author: Ben Skeggs <[email protected]>
Date: Sat Jul 14 19:09:17 2012 +1000
drm/nouveau/instmem: completely new implementation, as a subdev module
is the first bad commit. Standing on that commit, booting and then
starting X yields the output below. Hints are especially appreciated,
considering the patch is almost 8000 lines.
Thanks,
Henrik

Going through one suspend/resume cycle makes the corruption go away,
and there are no more errors in dmesg. Oddly enough, I have seen
something very similar when using i915 on the MBP10. Builtin modules
and systemd in both cases. Maybe this is a general drm issue. Any
thoughts?
Thanks,
Henrik

This is still a problem in Linus' tree. The screen corruption happens
during boot, in text mode, presumably in conjunction with alloction of
the nouveaufb device. It is 100% reproducible, and there is no
advanced graphics involved, just simple text console. Booting from efi
or bios does not matter. Modules are builtin.
Suspending and resuming once makes the problem go away every time.
Since this is a simple usecase, and the failing commit has been
bisected, it ought to be possible to find the problem. Unfortunately,
I am not familiar enough with the nouveau code to find the problem in
an 8000-line patch. Please help. :-)
Thanks,
Henrik
