Summary: HDMI gives no more signal

Severity: normal
Classification: Unclassified
OS: Linux (All)

This week I tried HDMI again on my system, and noticed it was completely
broken.
Got just no signal on my screen.
I knew it was working some months (and upgrades) ago.
After testing I found out the issue was introduced between kernel v3.14 and
v3.15.
Situation:
Insert HDMI cable into my laptop, and no signal on the external display.
The dmesg fills with errors also:
[ 186.210622] nouveau E[ PDISP][0000:01:00.0] INVALID_STATE [UNK08] chid 0
mthd 0x0080 data 0x00000000
[ 186.210627] nouveau E[ PDISP][0000:01:00.0] Core:
[ 186.210634] nouveau E[ PDISP][0000:01:00.0] 0x0084: 0x5dc34da1 ->
0x80000000
[ 186.210640] nouveau E[ PDISP][0000:01:00.0] 0x0088: 0x00000000
etc.
After some git bisect playtime, I found out the following commit caused the
issue:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/nouveau?id=05c63c2ff23a80b654d6c088ac3ba21628db0173
So I went back to stable 3.16 (Ubuntu Utopic version), and did a git revert for
that commit.
And yep, HDMI output was working again, and no more nouveau errors in dmesg.

Created attachment 106697
--> https://bugs.freedesktop.org/attachment.cgi?id=106697&action=edit
full dmesg
Attached a full dmesg.
The last lines are when I stop lightdm, and runpm stops the nvidia card.
This also causes shutdown to hang.

Seems like Ben fixed this issue:
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?h=linux-3.17&id=6fbb702e27d78ad2458df048b58cca3454bc0965
Used that commit on my kernel, and it fixes the issue!
Great! Thx!
