Summary: random - possibly Radeon DRM KMS related - freezes Product: Drivers Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-...@kernel-bugs.osdl.org ReportedBy: mar...@lichtvoll.de Regression: Yes Affected kernel versions: - 2.6.34-tp42-toi-3.1-04981-gb9a071a - 2.6.34.1-tp42-toi-3.1.1.1-04990-g3a7d1f4 Last kernel that worked: - 2.6.33.2-tp42-toi-3.1-lowmem-free-991-992-04964-gf00c7ec-dirty (including some patches to explicitely allow freeing lowmem pages on hibernation - I tested them for Nigel) Currently running kernel: - 2.6.33.6-tp42-toi-3.1.1.1-04982-g768d8a0 All from Nigel Cunnigham's TuxOnIce trees, but hangs happened before any hibernation cycle took place. So now I just report this although I do not have much information about the circumstances of these hangs. With 2.6.34 I had two and with 2.6.34.1 I had one sudden freeze of at least the desktop on my ThinkPad T42 with Radeon graphics. Mouse pointer just froze, Ctrl-Alt-F1 did nothing and AFAIR also there was no disk I/O anymore. I am not completely sure about the last one. Since the freezes happened in quite unpleasant circumstances I did not bother to start up a second machine in order to try to SSH into my T42. With 2.6.33.2 I did not experience those freezes. I used the tuxonice-2.6.34 tree from Nigel Cunningham, cause I prefer TuxOnIce over other hibernation methods. Since all of the freezes just happened after a fresh boot of the system without any snapshot cycle in between them, I believe this to be a mainline kernel bug. All freezes have been while running a KDE 4.4.4 desktop with OpenGL compositing enabled. The first two times just shortly after login in to the desktop. The third time while playing an AVI file from my photo SD card with Dragon Player. On the other hand I had hours of uptime with some TuxOnIce snapshot cycles without anything happening. I never had a freeze after the machine had done snapshot cycle. The freezes rather happened shortly after a fresh boot of the machine. I am not sure whether this is a Radeon DRM KMS related bug, but this is my best guess at the moment. Other activities involved in all three situations were: - USB. On the first two a M-Audio Sonica Theater was connected. On the third the kernel was reading the AVI file from a SD card connected via USB card reader. - eSATA harddisk. In all times an external 500 GB harddisk was connected via eSATA But also here I had the kernel running for hours with USB or eSATA without anything happening. In the further cause I will attach some hardware and software details that might be helpful. Currently I just downgraded to 2.6.33 again. I compiled me a 2.6.33.6. Since actually I really want some stability at least during the week where I hold a Linux training, I want to stick with it for now. Currently my plans are to wait for 2.6.34.2 or .3 and try again. The laptop is used for production work and I want it to meet some basic stability requirements. But if need be and I manage to take time for it, I may do some guided testing. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
