[drm:radeon_dvi_detect] *ERROR* HDMI Type A-1: probed a monitor but no|invalid EDID

[TommyBoy]

This is a show stopper with my 10.04 system that I am currently running on.

I have:
02:00.0 VGA compatible controller: ATI Technologies Inc RV630 [Radeon HD 2600 Series]
02:00.1 Audio device: ATI Technologies Inc RV630/M76 audio device [Radeon HD 2600 Series]

This is connected to a LCD TV using HDMi, running the latest kernel breaks the xserver and I am dripped out into the shell with the same error messages in the log below. I am writing this on the previous kernel version so it does work.

There is a patch upstream in kernel 2.6.35-rc1 which may help you. From the changelog:

commit 61e57a8d72f2336faf39b5d940215cf085e01e6e
Author: Adam Jackson
Date: Mon Mar 29 21:43:18 2010 +0000

    drm/edid: Fix secondary block fetch.

    This makes fetching the second EDID block on HDMI monitors actually
    work. DDC can't transfer more than 128 bytes at a time. Also,
    rearrange the code so the pure DDC bits are separate from block parse.

    Signed-off-by: Adam Jackson
    Signed-off-by: Dave Airlie

Unfortunately this has not been cc'd to the stable kernel branch.

Note that kernel 2.6.35-rc1 currently has a major performance regression, which will hopefully be fixed in 2.6.35-rc2.

[madbiologist (me-again)]

What happens if you simply update to the latest available 10.04 Lucid kernel?

[Noel Ferreira (noelferreira)]

Hi.

I have the exact same problem using ATI HD4350 and HDMI second monitor (32LG2000).
I have updated to the latest available kernel (2.6.32-24) in 10.04 Lucid kernel and the problem persists.
I don't know if i need to wait or try the patch in the source.

I would appreciate any help.

Thanks,

noel

[madbiologist (me-again)]

Try the 2.6.35-rc5 kernel PPA from http://kernel.ubuntu.com/~kernel-ppa/mainline/

I guess it's because it cant't get an EDID.

Hi.

Please let me know if you find any solution for this problem.
Thanks,

[sam tygier (samtygier)]

does disabling KMS help?
at grub press 'e' to edit. add 'radeon.modeset=0' to the end of the kernel line, and ctrl+x to boot

maybe related to Bug #601376

[MXIIA (mxiia93)]

I have this same problem...

[madbiologist (me-again)]

@MXIIA - What version of Ubuntu are you using?

[MXIIA (mxiia93)]

I am using 10.04 AMD64 version. I could post my dmesg and lspci if needed to help solve this issue.

[madbiologist (me-again)]

@MXIIA - Please try the 2.6.35.3 kernel PPA available at http://kernel.ubuntu.com/~kernel-ppa/mainline/ . If it doesn't resolve the issue please post your dmesg and the output of lspci -vvnn when using that kernel.

[MXIIA (mxiia93)]

I may have installed it incorrectly, but I installed the headers and the kernel for amd64 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35.3-maverick/ and upon booting I get "request_module: runaway loop modprobe char-major-5-1" as an error

[madbiologist (me-again)]

The error in comment #13 is beyond my expertise, but to install you only need to install the *image*.deb package that corresponds to your architecture. If you wish to install the headers as well you actually need to install 2 files , one containing the word "generic" and ending in the architecture type, and the other not containing the word "generic" and ending in the word "all". See https://wiki.ubuntu.com/KernelTeam/MainlineBuilds?action=show&redirect=KernelMainlineBuilds for further details.

[madbiologist (me-again)]

Or just https://wiki.ubuntu.com/Kernel/MainlineBuilds

[Omer Barlas (omer-barlas)]

adding radeon.modeset=0 in /boot/grub/grub.cfg to kernel line before "quiet" did solve my problem. after another kernel update, might have to do it again.

[genius (gennady-savchuk)]

This bug also affects me (Ubuntu 10.10beta, x86).
It shows itself as periodical hangs for a few seconds, after which following lines were found in syslog:

2sam tygier: thank you, the workaround help.

[bugssoren (paul-sorenassoc-deactivatedaccount)]

I also observed this with 10.10 AMD64 server version. With updates current as of January 10, 2011. In my case, I was using an Asus M2A-VM motherboard with AMD690G and SB600 chipset. This is a Radeon X1200 video equivalent.

I got around the problem by replacing the motherboard with one with a 785G north bridge. So the problem looks to probably be unique to the 690G in my original setup here.

Is there any way to solve it without disabling kms? There is another way but it also causes another error:

TommyBoy thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Friend,

Attorney General Jeff Sessions recently sent a letter to Congressional
leadership demanding that Congress set aside the Rohrabacher-Blumenauer
amendment, which protects states that have lawfully enacted medical
marijuana programs from federal interference.

It is apparent that the AG and the Justice Department is seeking to use
every tool at their disposal to roll back the progress that we have made to
provide patients legal access to medical cannabis. That is why, last week,
our allies in the US House and Senate introduced the CARERS Act of 2017,
which would codify Rohrabacher-Blumenauer protections into law and forbid
the Justice Department from overriding them.

*Click here to send a message to your members of Congress urging them to
stop Sessions’ War on Medical Marijuana before it starts.
<https://lists.norml.org/list/mail.cgi/r/news/568689376679/clintbrothers/gmail.com/>*

This bipartisan legislation explicitly exempts from federal prosecution
those who are engaged in the “production, possession, distribution,
dispensation, administration, laboratory testing, recommending use, or
delivery of medical marijuana” in instances where these activities comport
with state law.

Thirty states and the District of Columbia now regulate the possession,
use, and dispensing of medical marijuana by statute. It is time the federal
government acknowledge these laws and protect the patients who rely on them.

*Now is the time to protect patients, send a message to your Senators and
Representative to support the CARERS Act of 2017.
<https://lists.norml.org/list/mail.cgi/r/news/568689376679/clintbrothers/gmail.com/>*

The Senate bill was introduced by Senators Booker (D-NJ), Paul (R-KY),
Gillibrand (D-NY), Lee (R-UT), Franken (D-MN), and Murkowski (R-AK). The
House companion bill was reintroduced by Rep Young (R-AK) and Rep Cohen
(D-TN).

Medical marijuana is not a partisan issue - in fact, an overwhelming 94% of
Americans support the use of cannabis by authorized medical patients.
Nonetheless, militant prohibitionists including Jeff Sessions still believe
that “good people do not smoke marijuana.” It is our job to tell Congress
that this outdated mentality has no place in policy making decisions.
Attorney General Sessions is not a doctor and he has no bu...
