[i865] System Crash: VGA-1: EDID invalid.

[Javier Barroso]

Binary package hint: xserver-xorg-video-intel

After upgrading to karmic, my system is unstable.

1. kernel 2.6.31 makes my resolution settings to 800x600, and after login (I can't choose any major), I can't stay there 5 minutes. In syslog this message is showed when all the system but mouse movement crash (the mouse can move, but can't click anything). I have to use sysrq to reboot the system (not ctrl-alt-f1 works):

Now I can report this bug because I'm running old 2.6.27.

2. Without xorg.conf file my screen goes to intermitent (and the system is not capable to init Xorg)
I had to xorg -configure and copy xorg.conf to get a working xorg

3. Xorg top my system. It is eating all my cpu :( (all the time)
3093 root 20 0 158m 21m 6360 R 99 2.2 13:03.80 Xorg

I can't see any related with Xorg in syslog when it is eating 99% cpu:

Sep 29 00:35:25 pinochin pulseaudio[6747]: main.c: Falló el inicio del demonio.

pulseaudio and rtkit-daemon are continuosly giving me these errors.

What do you recommend ?

I was thinking karmic was near to be stable, but in my system it is not true :(

Thanks

[yakuizhao (yakui-zhao)]

Will you please attach the vbios.dump? The vbios.dump can be obtained by using the following commands.
    1. echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom
    2. cat /sys/devices/pci0000:00/0000:00:02.0/rom > vbios.dump
    3. /sys/devices/pci0000:00/0000:00:02.0/rom

Thanks.

[yakuizhao (yakui-zhao)]

From the dmesg log it seems that we can't get the correct EDID for LVDS and then it complains the following warning message:
   >drm:edid_is_valid] *ERROR* Raw EDID:

At the same time it seems that the system will check the state of LVDS and then try to get the supported mode periodically. But as it can't read the EDID correctly.

Maybe we should avoid to read the EDID for LVDS on this box.

Please attach the output of vbios.dump and dmidecode.

Thanks.

[Michael Fu (michael-fu-intel)]

[metellius (haraldhv)]

Sorry about the silence, real life stuff keeps getting in my way :)

Will now attach the requested data.

I see you have marked the bug as resolved, and even though it seems partially based on the fact that I disappeared, I will not attempt to change that back now. But know that I am still interested in helping out with this bug, even if I did a bad job at staying active until now...

Further comments: I just upgraded to the newest 2.8.99 drivers from svn, and the bug still persists (whatever may be causing it). I also did the cat 1 > /devices/...../rom as instructed above, before dumping these files.

Don't read the EDID for LVDS when the LVDS_EDID is unsupported in VBT

Will you please try the debug patch and see whether the issue still exists?
   From the vbios.dump it seems that the LVDS_EDID is unsupported in VBT. Maybe it is unnecessary to read the EDID for the LVDS on this box.

Thanks.

[Michael Fu (michael-fu-intel)]

there are cases that LVDS supports EDID but VBT is wrong.. why not use a flag in private structure to set that, if first take of reading EDID has been failed, we won't bother to read EDID again? nobody is able to hotplug a LVDS panel anyway :)

Even though , the problem is more likely because a buggy user space tool that keep asking for EDID...

I took this bug in my upgrade to karmic:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/438435

I hope info recollected by ubuntu-bug are ok, but tell me if more info are needed from any other source

Thank you !

[Javier Barroso (javibarroso)]

I'm too affected by https://bugs.freedesktop.org/show_bug.cgi?id=22936

I tried Option "SwapbuffersWait" "true", but it didn't work for me.

I tried 2.9 version from ppa, but happened again :(
[drm:edid_is_valid] *ERROR* Raw EDID:
<3>aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa ................

...

If I try start without any "xorg.conf" my screen will blink and I have to press CNTRL-ALT-SUPR. X won't start.

I can read then, "vt: argh driver_data _became_ NULL" from my console

If I try running with VESA, it tell about different ABI versions from xserver-xorg and xserver-xorg-video-vesa , is it another bug ?

Thanks

This is dup from

I'll try to collaborate there (and here) ...

mmm, now I'm running xserver-video-intel-2.4 from siretart ppa, and it is working fine with 2.6.31 kernel (no more 99% cpu usage).

And in my dmesg I can still see:

So this error was managed correctly by previous video-intel versions.

Created an attachment (id=30614)
try the debug patch to get the process which always tries to read EDID

will you please try the debug patch and attach the output of dmesg?
Thanks.

I came to this bug from a ubuntu bug:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/475756

This bug is similar in that I see EDID output in the xorg.0.log multiple times. It is different in that the driver never attempts to read the EDID from the DVI1 port because it thinks the port is not connected. However I see the screen activate on boot so the connection is there.

This could be the same or different bug, so before I spam the comments with a whole bundle of attachments, tell me if you want me to put the information in here or in a new bug.

Mike, you issue is dup of bug# 23842, not related with this bug. pls try the patch over there. thanks.

[yakuizhao (yakui-zhao)]

since there is no response for more than one month, this bug will be rejected.

If the problem still exists, please try the debug patch in comment #27 and re-open this bug.

Thanks.

So I tried the 2.9.1 build of the Intel driver (via xorg-edgers Ubuntu ppa) and I still have this problem. dmseg prints out tons of EDID Invalid messages and I cannot use dual monitors on my 945GM chip.

Unfortunately I also had to downgrade back to 2.9.0 and all related packages because what came on xorg-edgers was very unstable. I will try to build 2.9.1 from source and do what I can to help you get to the bottom of this.

Will you please try the debug patch in comment #27 and attach the output of dmesg on your box?

Thanks.

[Freedesktop-jameskilton (freedesktop-jameskilton)]

Created an attachment (id=32070)
dmesg output w/ the dump_stack patch

My case is slightly different from the original poster now that I look at it. I don't get a spew of EDID invalid messages, but every time my system does something to try to read the EDID (say, running xrandr -q), a new EDID Invalid message shows up.

That said, it does appear that there are successful calls to drm_get_edid, as this attached file contains quite a few call stacks that are not followed by an EDID error.

Let me know if there's more information you need.

[Freedesktop-jameskilton (freedesktop-jameskilton)]

Any update on this? I even tried the "Don't read the EDID for LVDS when the LVDS_EDID is unsupported in VBT" patch, but nothing changed (still no recognition of other monitor, still EDID Invalid error).

[metellius (haraldhv)]

Created an attachment (id=32493)
dmesg output with patched kernel

I'm sorry for taking so long with getting this done, it was surprisingly complicated to get the kernel compiled on another pc and finally installed here.

In any case, I applied the debug patch and have a backtraced dmesg output ready for you, here it is.

[yakuizhao (yakui-zhao)]

Created an attachment (id=33190)
ignore the LVDS edid when it is unavailable or invalid

Will you please try the attached patch and see whether it still frequently reports the following message?
   >i915 0000:00:02.0: LVDS-1: EDID invalid.

thanks.
    Yakui

[metellius (haraldhv)]

Thanks a lot for your patch. No, with this patch it does no longer report the message frequently, only once as a part of kernel boot.
I can also happily report that there is no freezing, and for the first time in at least a year, I can actually play a video smoothly all the way through! :)

Please let me know if there is anything more you would like to test before you commit the patch.

[yakuizhao (yakui-zhao)]

Created an attachment (id=33486)
try the updated pathc that ignores the LVDS edid when it is unavailabe or invalid

Will you please help me test the updated patch again?

thanks.

[metellius (haraldhv)]

Applied and tested, it runs fine, still without the bug. Not sure if there is anything else I should look for?

[Sitsofe Wheeler (sitsofe)]

I can confirm that this patch worked for me too (Toshiba Portege M400, graphics card 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03), 2.6.33-rc8-00113-gf8b55f2 running on Fedora 12).

Now the corresponding patch is already shipped. And after the patch is applied,
it can avoid the warning message of "drm:edid_is_valid" perodically.

commit bfac4d6725baacbfc085c38e231b8582a1b8f62b
Author: Zhao Yakui <email address hidden>
Date: Wed Apr 7 17:11:22 2010 +0800

    drm/i915: Ignore LVDS EDID when it is unavailabe or invalid

So this bug will be marked as resolved.

Thanks.
