Hello, I'm not running -STABLE, but 5.2.1-p9. Perhaps someone could advise where I should start digging regarding problem I'm facing.. The problem follows: [long preface] I have pretty standard workstation (AMD Athlon XP 2400+/Nvidia GeForce2). Currently, I'm using KDE3 (latest from ports) as desktop environment. Suddenly, after upgrading system from qt3.3.2 to qt3.3.3, and XFree86-4.3.0 to XFree86-4.4.0 (also from ports), X server started randomly freezing after some period of time (could freeze after 20 mins, or after 24 hours/etc). I, first, suspected it is related to the upgrade of XFree86, so I went ahead to read /usr/ports/UPDATING on how to switch to X.org. Same day I flawlessly switched system from XFree86-*-4.4.0 to xorg-*-6.7.0_3. After running xorg for few hours, it also freezed the same way XFree86 did. I did pretty standard things I usually do - worked in konsole, used konqueror/mozilla/etc, and this time I had xmms playing something over local NFS server. After X freezed, I noticed that xmms still plays music, which brought me to thought that system is still running. Tried to switch from X to console (C+A+F<1-4>), but no luck. I went to my friend's room, and was able to SSH into my system. First I ran "top", and noticed that "Xorg" eats up all processor time. Next thing I did - I ran ktrace against Xorg's pid, and then "kill -9" Xorg. After killing Xorg, I went to my room and basically I could not do anything on the monitor - it just had my X session hanged on it. So reboot.. [problem] I have attached kdump output (the first 100 lines of it), which contains only the following lines: 76877 Xorg RET gettimeofday 0 76877 Xorg CALL gettimeofday(0xbfbfe798,0) I also would like to note that I tried switching between nvidia drivers, but it did not result anything - X still freezes. I would appreciate any suggestions/advises on this matter. [output of kdump is attached]
