v3.6.0+ @ the commit that caused the regression
The following commit causes KMS initialisation to result in a scrambled screen
with mostly blue elements. The screen responds to changes based on actual
content (e.g. system booting, lightdm starting).
drm/nouveau/clock: pull in the implementation from all over the place
I have tested and verified this regression on a 3.6 tree and the recent v3.7
tree pulled from git.kernel.org.
Below you will find some more data about my VGA card.
Attached you will find two dmesg output logs (don't know if they differ):
both are from the v3.7-rc1 tree (they are noted as 3.6.0+ in the logs)
dmesg-good.txt @ the commit before the one that caused the regression
dmesg-bad.txt @ the commit that caused the regression
