Similar by symptoms bugs were described here: http://bugs.freedesktop.org/show_bug.cgi?id=8666 http://bugs.freedesktop.org/show_bug.cgi?id=473 1. How to reproduce: start sauerbraten, play in ffa MP mode, jump much and shoot much, then get console lock in 7-15 minutes. Cube works well for hours ;-) 2. What report application: mga_get_buffer_ioctl: flush return = Device or resource busy (16), flags = 0x00000006 3. What reports Xorg (>3000 times): (EE) MGA(0): [dri] Idle timed out, resetting engine... 4. What can i do: ssh from other system to this locked, then reboot it. I can't switch to other VT (Ctrl-Alt-F2 for ex.), after such attempt system hangs. 5. System info: - MB: ASUS A7V-E VIA133 - Video: Matrox G450 32Mb AGP 2xVGA; 6.

Same problem with latest software: - Xorg 7.2 - mga_drv 1.4.6.1 - Mesa 6.5.2 - kernel 2.6.20 - Matrox card BIOS - latest I tried to disable buggy for me COMPOSITE extension, bug still exist.
Tried latest drm from freedesktop.org git reposotory and disabled preemption in kernel, still no results. P.S. Does someone read my messages or this bug list is dead? Seriously.
(In reply to comment #2) > Tried latest drm from freedesktop.org git reposotory and disabled preemption in > kernel, still no results. What AGP mode are you using? I know that there are some buggy interactions between MGA and certain Via chipsets. Have you tried 1x? > P.S. Does someone read my messages or this bug list is dead? Seriously. Yes, sorry. I just haven't had a chance to dig into it yet.
> What AGP mode are you using? I know that there are some buggy interactions between MGA and certain Via chipsets. Have you tried 1x? Moreover, i've tried next configuration: - no matroxfb; - no mga_vid; - no i2c; - no preemption; - no options for section "Device" in /etc/X11/xorg.conf except "AGPMode" "1" and "DRI" "True"; - disabled AIGLX and Composite extension. I've checked that all options is setted via dmesg and Xorg.log. Bug still here :( I've tried to debug and got 332Mb file, i see this in the end of it, repeating many times: Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] ret = fffffff0 Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x6442, nr=0x42, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_do_dma_reset] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x40086441, nr=0x41, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_dma_flush] flush, idle, Mar 15 04:44:32 mmx kernel: [drm:mga_do_wait_for_idle] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] ret = fffffff0 Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x40086441, nr=0x41, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_dma_flush] idle, Mar 15 04:44:32 mmx kernel: [drm:mga_do_wait_for_idle] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] ret = fffffff0 Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x6442, nr=0x42, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_do_dma_reset] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x40086441, nr=0x41, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_dma_flush] flush, idle, Mar 15 04:44:32 mmx kernel: [drm:mga_do_wait_for_idle] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] ret = fffffff0 Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x40086441, nr=0x41, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_dma_flush] idle, Mar 15 04:44:32 mmx kernel: [drm:mga_do_wait_for_idle] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] ret = fffffff0 Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x6442, nr=0x42, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_do_dma_reset] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] pid=1031, cmd=0x40086441, nr=0x41, dev 0xe200, auth=1 Mar 15 04:44:32 mmx kernel: [drm:mga_dma_flush] flush, idle, Mar 15 04:44:32 mmx kernel: [drm:mga_do_wait_for_idle] Mar 15 04:44:32 mmx kernel: [drm:drm_ioctl] ret = fffffff0
