Created attachment 602170 [details] /var/log/messages of 3.5.0 and 3.4.6. Description of problem: Today's update of kernel from 3.4.6-2.fc17.i686 to 3.5.0-2.fc17.i686 causes my screen to show many big black rectangular-ish areas. They are not fixed, but they come and go when I open or move windows on the desktop. I have a fully updated Fedora 17 system using KDE. Moreover, the laptop does not poweroff nicely anymore. I need to use the power button. This is a Thinkpad R50, with 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02) Version-Release number of selected component (if applicable): kernel-3.5.0-2.fc17.i686 How reproducible: Always Steps to Reproduce: 1. Select 3.5.0 in grub 2. Log on my account Actual results: Background is not completely repainted, it contais a few big black rectangular areas. Expected results: Normal background as in 3.4.6 Additional info: I attach /var/log/messages containing 2 full cycles with 3.5.0 and 3.4.6.
I've tried with official kernel 3.5.0 + localmodconfig and black areas are the same. Only advantage is that it powers off properly. Reading inside the /var/log/messages I was only able to find some cosmetic differences in the [drm] sections, when the names have a "-1" at the end. 3.4.6 [drm] Connector 0: [drm] VGA [drm] DDC: 0x60 0x60 0x60 0x60 0x60 0x60 0x60 0x60 [drm] Encoders: [drm] CRT1: INTERNAL_DAC1 [drm] Connector 1: [drm] DVI-D [drm] HPD1 [drm] DDC: 0x64 0x64 0x64 0x64 0x64 0x64 0x64 0x64 [drm] Encoders: [drm] DFP1: INTERNAL_TMDS1 [drm] Connector 2: [drm] LVDS [drm] Encoders: [drm] LCD1: INTERNAL_LVDS [drm] Connector 3: [drm] S-video [drm] Encoders: [drm] TV1: INTERNAL_DAC2 3.5.0 [drm] Connector 0: [drm] VGA-1 [drm] DDC: 0x60 0x60 0x60 0x60 0x60 0x60 0x60 0x60 [drm] Encoders: [drm] CRT1: INTERNAL_DAC1 [drm] Connector 1: [drm] DVI-D-1 [drm] HPD1 [drm] DDC: 0x64 0x64 0x64 0x64 0x64 0x64 0x64 0x64 [drm] Encoders: [drm] DFP1: INTERNAL_TMDS1 [drm] Connector 2: [drm] LVDS-1 [drm] Encoders: [drm] LCD1: INTERNAL_LVDS [drm] Connector 3: [drm] SVIDEO-1 [drm] Encoders: [drm] TV1: INTERNAL_DAC2
I have same problem on a Thinkpad R50

The same on another Thinkpad T41. The same hardware as listed by Taunus.
I've opened a bug @ freedesktop. There you can find more information. I managed to bisect the issue and I found that passing radeon.modeset=0 to the kernel avoids this issue (but there is not XV support in X). Please report your experience over there as they should be in a much better position to understand the problem.
Same problem here with HP NC8430. The radeon.modeset=0 helps, but also results in a lower screen resolution 1400x1050 instead of 1680x1050. Also potentially relevant: there is long wait (10 seconds) during boot when the display is black. Looks like the lockup_timeout is exceeded or so.
Upstream bug has been fixed for me. Check out http://bugs.freedesktop.org/show_bug.cgi?id=54129

Works for me as well.

(In reply to comment #2) > I have same problem on a Thinkpad R50 kernel-3.5.4-2.fc17 works for me. Thanks.
Not sure why bodhi didn't close the bug.
