[Bug 38382] New: radeon: wait for empty RBBM fifo failed

https://bugzilla.kernel.org/show_bug.cgi?id=38382 Summary: radeon: wait for empty RBBM fifo failed Product: Drivers Version: 2.5 Kernel Version: 3.0.0-rc4 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri(a)kernel-bugs.osdl.org ReportedBy: stavallo(a)unina.it Regression: No Created an attachment (id=63662) --> (https://bugzilla.kernel.org/attachment.cgi?id=63662) dmesg with pageflipping disabled My system is affected by frequent oopses that makes it unusable. There are no problems when the X server is not launched, but when it starts (with KDM) something bad soon happens. If I don't login into KDM, it may freeze after few minutes. If I login, an oops happen after few minutes. Unfortunately I can't tell exactly when this behavior started to happen, but somewhere between 2.6.39 and 2.6.39.1. Yesterday I compiled the kernel from git but no luck. I tried to disable pageflipping (as suggested in bug #32402) but the oops happened again. WIth pageflipping disabled, I managed to ssh into the machine and get dmesg and Xorg.log (attached). Unfortunately, I didn't manage to ssh into the machine with pageflipping enabled. I have a Radeon X300 card and I am using mesa git from 20110616, libdrm 2.4.25 and Xorg 1.10.2. If I need to test anything, please let me know, thanks. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.

[Bug 37502] New: Kernels oops display in X leaves screen garbled

Switching to a virtual console, and back to X (twice) restored my desktop. I don't know if the kernel is trying to switch to a text console to display the Oops, or if it tries to display the oops on the graphical console, but apparently its not working well. The first time I get an Oops after a reboot I get to see the Oops text on a black background (and my mouse cursor, which makes me believe this is the graphical KMS console), but everything after that just leaves me with a garbled screen. The oops displayed is: https://lkml.org/lkml/2011/6/15/50 I don't know if this is a regression or not, I rarely get Oopses, and last time I got a panic message I was able to see it (although I was in X at the time), but then so can I for the 1st Oops message. My graphics card is: 01:00.0 VGA compatible controller: ATI Technologies Inc RV730 PRO [Radeon HD 4650] I use KMS, Xorg 1.10.2, and Mesa 7.10.2-3. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.

A TV is attached to the S-Video port through a generic S-Video multiplexer, the others are not connected. TV is a US/NTSC standard definition CRT. System boots into a VGA text console with no problem. When attempting "modprobe radeon", the system switches to graphics mode, then prints a backtrace on the framebuffer and hangs (no keyboard response, no ping, ssh dies). A mostly-solid stripe of green pixel noise can be seen across the bottom 2 or 3 scanlines of the TV. The setup works when using the fglrx driver. An NV31+nouveau arrangement also seems to work, so I don't think the motherboard is at fault. This isn't really a "regression" per-se, as it has never worked in any vendor- or self-compiled kernel I've tried (since about July 2010). -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.

[Bug 31712] New: GPU lockup CP stall after resume from hibernation

https://bugzilla.kernel.org/show_bug.cgi?id=31712 Summary: GPU lockup CP stall after resume from hibernation Product: Drivers Version: 2.5 Kernel Version: 2.6.38 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri(a)kernel-bugs.osdl.org ReportedBy: psusi(a)cfl.rr.com Regression: No When resuming from hibernation on my Asus P8P67 Pro Core-i5 2500K system with a Radeon 4850, I get a GPU lockup CP stall error, which leaves the display in a corrupt state. The kernel attempts to reset the display to no avail, landing back in the lockup again and again. A sysrq-K to kill X.org resolves the issue. The issue seems to be tied to plymouth. If I boot without the quiet and splash options when resuming, it resumes just fine. Suspend also works fine. This occurs with the stock Ubuntu Maverick 2.6.35 based kernel, the Natty 2.6.38 based kernel, and the Linus 2.6.38 kernel ( last two built from source ).
