This laptop, has only one standard video connector (VGA) along with the lcd screen. With 3.1-rc9+ plus airlied's drm-next on bootup bios init the screen, kernel boots in text mode fine, but when KMS takes over the screen goes blank. (the external VGA connector also goes blank). (running latest git of xorg-ati/mesa) interesting from dmesg; [ 32.534186] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 104 [ 32.534191] Raw EDID: [ 32.534194] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.534196] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.534198] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.534199] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 70 [ 32.534201] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.534203] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.534205] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.534207] 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 08 [ 32.589038] [drm:radeon_dp_i2c_aux_ch] *ERROR* aux_ch invalid native reply 0x70 voodoo@a53t:~$ ls -lh /lib/firmware/radeon/TURKS_* -rw-r--r-- 1 root root 24K 2011-10-06 22:26 /lib/firmware/radeon/TURKS_mc.bin -rw-r--r-- 1 root root 5.4K 2011-10-06 22:26 /lib/firmware/radeon/TURKS_me.bin -rw-r--r-- 1 root root 4.4K 2011-10-06 22:26 /lib/firmware/radeon/TURKS_pfp.bin Regards,

Created attachment 52866 [details] [review] possible fix patch 2/2. Do these patches help?
Awesome! Thanks Alex. KMS is now works perfectly on this laptop.. Using v3.1.0 + airlied's drm-next pull for (3.2) Patch 2 was missing another change you had posted, so it didn't apply: http://people.freedesktop.org/~agd5f/0009-drm-radeon-kms-rework-DP-bridge-checks.patch and that patch missed one of the function conversions, so i'm posting a git-format patch dump of the 4 patches I used here: http://rcn-ee.homeip.net:81/testing/asus-a53t/a4-kms/ Thanks,
As I said to Alex on IRC, these patches also solves the issue on Toshiba laptops: C670D-10C (AMD E-240) and C670D-11K (AMD E-450). (Old reference: https://bugzilla.kernel.org/show_bug.cgi?id=34822 ) Just putting that out there.
These patches may fix some systems, but they also cause a similar problem on my HP ProBook 6465b (A6-3410MX processor with built-in GPU). There is also someone else with the same issue on different ProBook model: http://forums.gentoo.org/viewtopic-t-908460.html Reverting the patch from comment #6 fixes it at least for me. Either way, it is bad for Zathras. :-)

Please attach your xorg log and dmesg output.
Created attachment 55400 [details] dmesg/system log I deleted the buggy kernels already, but here is the system log from a boot with one. It should have full dmesg output in it.
Created attachment 55401 [details] [review] Xorg log I don't think Xorg log is relevant here, but since you asked one, I'm attaching it anyway. This is from working system. The bug happens when the console switches from text mode to graphics mode during boot, so I cannot startx or even log in except with ssh.
Do these patches work for everyone? http://people.freedesktop.org/~agd5f/dce_fixes/ They are against drm-next or Linus' tree.

Unfortunately those dce fixes regress my asus a53t laptop.. Using Linus's current top of tree with those 4 patches.. Attached dmesg/xorg.log Is it too early to for qwerk table for these laptops? ;) Regards,
HP 4535s - patches from comment#13 work perfectly. Kernel 3.2.
A patch referencing this bug report has been merged in Linux v3.2-rc1: commit cf2aff6eff251b6fbdaf8c253e65ff7c693de8cd Author: Alex Deucher <alexander.deucher@amd.com> Date: Fri Oct 28 16:07:36 2011 -0400 drm/radeon/kms: fix DP setup on TRAVIS bridges
Normal 3.2 kernel doesn't work for me. I tried Debian's 3.2rc7 and Aptosid's 3.2 kernels - they don't work. So seems like the patches haven't been merged into 3.2. Maybe not all of them have been merged, there are 4 patches. I have applied all 4 to my kernel and it works. And I don't think that Debian or Aptosid maintainers have deleted some patches from the original kernel - maybe they have added some but not deleted.
I am the author of https://forums.gentoo.org/viewtopic-t-908460.html , do you need any additional info, logs?
Created attachment 56457 [details] [review] fix travis setup Does this patch do the right thing for everyone's platform? Patch should apply against Linus' master or Dave's drm-fixes branch.
Alex, The patch (in comment 22) on top of v3.2.2 works fine with kms on my Asus a53t.. Regards,
