16.04.2 LTS (4.4.0-62-generic) now spewing EDID vga radeon errors

[Zachary Burns]

I've just performed an "apt-get update" on a Dell 2950 Server - which was already running 16.04.1 and now it's spewing EDID errors - I'm not sure what changed from 16.04.1 to 16.04.2......

I've attached dmesg to this, but basically it's dumping the following in logs and to the screen.

[drm:radeon_vga_detect [radeon]] *ERROR* VGA-1: probed a monitor but no|invalid EDID

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I've recently installed Ubuntu 16.04.2 Server Edition on DELL Poweredge 2950 and the syslog is filling up with,

"[drm:radeon_vga_detect [radeon]] *ERROR* VGA-1: probed a monitor but no|invalid EDID"

above message every 10 sec.

Just reading through I noticed that Joseph Salisbury wanted reporter to test out the latest upstream kernel and never received the feedback.
Should I test out the kernel now? Or should I start a new bug report?

[dann (ktdann)]

While waiting for any one of you guys to return, I'm going to go ahead and test out the upstream kernel by downloading below files,

linux-headers-4.15.0-041500rc4_4.15.0-041500rc4.201712172330_all.deb
linux-headers-4.15.0-041500rc4-generic_4.15.0-041500rc4.201712172330_amd64.deb
linux-image-4.15.0-041500rc4-generic_4.15.0-041500rc4.201712172330_amd64.deb

[dann (ktdann)]

I tried the upstream kernel 4.15 but no luck. Error still exists.

By the way, how to I tag it "kernel-bug-exists-upstream" and mark it "Confirmed" ?

[dann (ktdann)]

TAG: kernel-bug-exists-upstream

[Kai-Heng Feng (kaihengfeng)]

Please file an upstream bug at https://bugs.freedesktop.org/
Product: DRI
Component: DRM/Radeon

[dann (ktdann)]

I went ahead and tried to file an upstream bug at bugzilla but apparently this bug has previously been reported and fixed.
Anydoby interested can go and read the link below.
https://bugs.freedesktop.org/show_bug.cgi?id=34457

Basically this is what you have to do.
QUOTE
"Either upgrade your system to Ubuntu Oneiric or install the fixed kernel (with backported kernel patches) from Launchpad PPA for Ubuntu Maverick.

Both solutions will fix the problem, as it did for the others having this special buggy chipset."
END OF QUOTE.

Thank you.

FWIW, I just finished installing Ubuntu Server 16.04.02 and then upgrading it to the latest on Jan 11, 2018. I have a command line only system (it is just a really basic firewall) and the keynel is logging messages like this:

Jan 11 09:23:42 speedy2 kernel: [64428.303428] [drm:radeon_vga_detect [radeon]] *ERROR* VGA-1: probed a monitor but no|invalid EDID

every ten seconds. I am using an old VGA monitor because I really don't need a screen unless something goes wrong, but sadly, the only thing currently wrong is that the kernel won't shut up about the monitor! So, I leave the monitor unplugged until I need it in order to keep the noise level down. I wonder if the radeon driver will ever be fixed for this?

[Kai-Heng Feng (kaihengfeng)]

Please try latest mainliner kernel.
