[RS600] video freeze with KMS (X and plymouth) (upstream patches available)

Hi Rafi,
avivotool can be used to assist in debugging this issue. avivotool is provided with the radeontool package, so to install it run:

    sudo apt-get install radeontool

After installing it, you run it like this:

    avivotool regs all > regdump_good.txt
    avivotool regs all > regdump_broke.txt

Run it two times. Once when you have a working screen (for any driver), and once in the broken case (either from the tty console or logged into the sick box remotely). Attach both of those to this bug report, and we can then forward this issue upstream. Thanks ahead of time!

This commit for the kernel is the fix for these RS600's that cannot boot with KMS

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=32b3c2abaf8c61c80a8b02071c73f05252122ffe

Simple enough patch, severe enough issue. Looks worth an SRU for Lucid.

This commit also looks worth pulling for RS600 fixing: http://lists.freedesktop.org/archives/dri-devel/2010-April/000094.html

This happens to me on my Dell Latitude XT.

I also have and RS600 as a graphics cards, and I also run into problem always installing ubuntu 10.04, when I run a live session from cd all is ok, but when I do an install, it doesn't boots. Also when I did a 9.10 -> 10.04 update.

So with this fix problem will be solved?

I should perform a clean install, or updating from ubuntu 9.10?

The commit bryce mentioned in comment #5 is in 2.6.33.3

Can you please try the lucid kernel with the patch in

http://people.canonical.com/~manjo/lp544590-lucid/

and report back here? If that works I will submit SRU for lucid.

This has fixed my problem.

01:05.0 VGA compatible controller: ATI Technologies Inc Radeon Xpress 1250

before using the patched kernel it would only boot with radeon.modeset=0

Patch submitted for SRU in lucid.

Fix is upstream and was included in 2.6.34. The stable tree for 2.6.33.y is expected to get discontinued soon. So this is a fix might not come back via any upstream stable update.

Fix was part of 2.6.34 and is included in Maverick.

Accepted linux into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I've been experiencing this bug too, on an integrated Radeon HD 2100:

01:05.0 VGA compatible controller: ATI Technologies Inc Radeon 2100

The fix from proposed seems to have solved it.

This bug was fixed in the package linux - 2.6.32-23.37
