FreeBSD 6.3-PRERELEASE #5: Sat Dec 29 19:25:43 CST 2007 i386 I've noticed that this system is freezing periodically, for anywhere from around a fraction of a second up to perhaps 1.5 seconds, and occurring on average about twice a minute, but with no particular pattern - i.e. it could happen twice in fairly quick succession, or not for 40-50 seconds.
By running glxgears the problem is easily witnessed, also by maintaining the mouse in constant motion, and it was originally noticed during normal use when, e.g. the system momentarily becomes unresponsive to keyboard input. I've now also witnessed it by running top with a delay setting of zero and displaying system processes. The shorter delays are not easily spotted but the longer delays are. This was seen both in a terminal session and at a console. Using top also revealed another interesting phenomenon - the 'top' display freezes for very brief periods, probably less than 0.1s, but quite regularly, at around once per second. Seeing this prompted me to realise that glxgears stutters in what appears to be a corresponding way. This behaviour (the freezing itself) is not entirely consistent, either. Just while I've been writing these paragraphs I've noticed glxgears' behaviour range from stuttering at around once per second, to around twice per second, to not doing it (perceptibly) at all. I now realise that I've actually witnessed this behaviour in glxgears for quite some time, extending back into the distant history of this system, which may include 6.0-RELEASE but would certainly include a few different revisions in the 6.x series. It has been always source-upgraded since the original install. I'd always just thought that it was some hiccough in the graphics system. Ports were recently upgraded so it is now running xorg-7.3_1, gnome-2.20.2, nvidia-driver-96.43.01. The system has been up for 5 days now and is quite loaded up with applications at the moment and is normally left running. Currently it has running (on gnome): evolution, firefox-devel (with some dozens of windows and tabs open), xmms, gimp, xchat, eclipse-devel, gedit, a handful of terminal sessions. It's running a custom kernel - mainly raid and unused network drivers removed - mods listed below. The hardware is a Gigabyte GA-8SQ800 motherboard (SiS), with a 2.4GHz P4, 1.5GB DDR, nVidia MX440 AGP graphics, RTL-8139 network, AHA-2940 SCSI controller (for a scanner), 2 x 80GB ATA disks. This system has also had a tendency at times to crash when switching VTs between console and xorg. This problem has varied in consistency with the different incarnations of OS and nvidia-driver versions and hasn't yet occurred with this latest update. I'd really appreciate any suggestions to help identify what's going on here.
