Summary: X server crashes with a SIGBUS on Evergreen Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: critical Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: tomasz.figa@gmail.com
I have recently switched my desktop PC with Radeon HD 5770 from fglrx to xf86-video-ati and discovered a problem causing the X server to crash with a SIGBUS signal.
I can reproduce this bug by opening a PDF document in Okular and scrolling through several pages back and forth, then mouse cursor hangs and X server crashes. It happens regardless of kernel version.
Disabling RenderAccel helps, but it's not a solution since it turns off the acceleration.
It's not a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=29738 , because it still happens with pre-709ea97145c125b3811ff70429e90ebdb0e832e5 kernels.
My setup:
Linux 2.6.35.4, git drm-fixes or git drm-radeon-testing xorg-server git 09/13 xf86-video-ati git 09/13 libdrm git 09/13
Intel Core 2 Quad Q6600 Processor AMD Radeon HD 5770
