hi hackers, I'm trying to find out what is causing deadlocks on my system. it's an EPIA EN1200E with kernel 2.6.24-1-686 from debian lenny and i'm using xorg gdm gnome @1280x1024 with the maximum videoram setting selectable in the bios =64MB I use openchrome default settings but activedevice=crt,dvi (I use the dvi daughter board) I've 1GB ddr2 533 100% ok memtest86-ed several times.
my openchrome svn revision is currently: 532. I've configured ttyS0 as serial console so I can see outputs on a nullmodem terminal (like kernel panics). I presume a memory corruption, buffer overflow, or something similar because when I play (fullscreen seems worse) a video in XV or, worse, XVMC using different player engines (xine, ffplay, mplayer, ...) I quickly get a system deadlock with a panic reported on the serial console. with XV I must run several videos before I can get a d-lock, with XVMC often I need only one to kill all. when the system is locked the screen is freezed and the last second of the audio is looped forever. when I play using x11 output, I've not any problem (but it's slooow :D) I was able to copy by hand on paper this console output from an imminent lock: [drm:via_cmdbuf_wait] *ERROR* via_cmdbuf_wait timed out hw 179900 cur_addr f9800 repeated many times with different "cur_addr" values. almost always I can read a kernel panic about ata dma error... but I do not believe it's an ata problem: If I do not start X at all, my system could run for months w/o problems, and I tried also to play a movie with mplayer from command line and -vo dummy to verify under heavy loads. instead, if I run a video with XV under xorg without any apparent problem, the system become unstable also when I close the player and do other tasks (max uptime I can get after a video is ~15 days). this is why I presume a memory corruption somewhere triggered by playing a video in XV or XVMC. kind regards, I'm ready to help you solving this issue by sending logs or performing tests. _______________________________________________ openchrome-users mailing list [email protected] http://wiki.openchrome.org/mailman/listinfo/openchrome-users Main page: http://www.openchrome.org Wiki: http://wiki.openchrome.org User Forum: http://wiki.openchrome.org/tikiwiki/tiki-view_forum.php?forumId=1
