https://bugzilla.kernel.org/show_bug.cgi?id=92891 Bug ID: 92891 Summary: Maschine hangs forever at loading the radeon module Product: Drivers Version: 2.5 Kernel Version: v3.14.31-rt28 / e1a0d6d8b023c54a5677310e68222e7a58b11f91 / linux-stable-rt Hardware: All OS: Linux Tree: PREEMPT_RT Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: georg@xxxxxxxxxxxxxxxx Regression: No Created attachment 166041 --> https://bugzilla.kernel.org/attachment.cgi?id=166041&action=edit Kernel config Hi all, recently i changed my Gfx card from a evergreen/hd5770 to a pitcairn/r290 (Chipset: "PITCAIRN" (ChipID = 0x6811)). 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Curacao PRO [Radeon R9 270] [1002:6811] On a second partition a realtime system without any problems. The system ran for a year with the kernel 3.10.20-rt17 perfect fine. Now as i updated my hardware with the new gfx card i started the RT system, i assumed the problem is the gfx card driver. I updated the kernel to the latest in git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git . The first try was v3.14.31-rt28. But it froze like the old (v3.10.20-rt17) kernel. After some testing i found out that the old (3.10) and the new (3.14) kernel start the machine when i disable KMS (radeon.modeset = 0). The exact point in the startup procedure is "Waiting for uevents". At this stage udev get started and loads the modules. After testing various kernel versions i picked 3.14.31-rt28 this did start the machine without the commandline "radeon.modeset=0" and i thought i have a working commit, but X did not start and i tried to load the module manually. At this point (modprobe radeon) the machine froze again. I attached the old evergreen card in the machine and tested with this card what configuration runs. I got the following results: Evergreen: v3.10.20-rt17 Ok v3.14.20-rt17 Not Ok (freeze) Pitcairn: v3.10.20-rt17 Not Ok (freeze) v3.14.20-rt17 Not Ok (freeze) So i just filled this bugreport against the newest version i tried. What info should i add? -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
