Doesn't seem to cause any problems, is this worthy of "*ERROR*"?

Does the GPU work as expected?

[Cristian Aravena Romero (caravena)]

GPU work fine. Not problem for work.

Problem with message -> "scares" to user :-S

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Daniel Letzeisen (dtl131)]

I agree. Although this information is useful to developers, it scares users to see '*ERROR*' when they boot, and the error message doesn't doesn't necessarily mean that anything important to the user is wrong.

[Daniel Letzeisen (dtl131)]

@jsalibury: I was typing my comment and changing status to triaged when you set it to 'incomplete' (I didn't mean to "override" your status change). What other information do you want from the OP?

Still present with kernel-4.0.5-200.fc21.x86_64:

[drm:radeon_get_legacy_connector_info_from_bios [radeon]] *ERROR* Unknown connector type: 8

[Alexdeucher (alexdeucher)]

Probably a bios bug. What physical connectors are actually on the board?
