Basically the system just stops dead -- mouse frozen, nothing moving on screen (although the display stays on), no response to keyboard or network, no log messages, no panics, nothing. Have to hit the reset button to get things moving again. Happens maybe once or twice a week, usually when the machine is pretty much idle. This is with -STABLE from about 2 months ago, although it was happening before that. All slightly embarrassing, since I've recommended this board to people on the grounds that it was extremely stable :-( It doesn't seem to be a temperature-related thing... mbmon reports the CPU temperature somewhere between 44-54C depending on room temp, usually less than 50C. It'll run up to around 60C doing a buildworld on a hot day, but I've never had it lockup while doing that. I suspect it's maybe a chipset compatibility issue. This board has an AMD761 north bridge and a VIA 82C686 south bridge. The latter has caused all kinds of PCI & ATA problems in the past -- the ABIT BIOS supposedly does the right thing to avoid these, and I know FreeBSD has workarounds as well, but you never know. Interestingly, I was able to lock the thing up three times in rapid succession by (attempting to) dd /dev/zero onto a nasty old 500MB disk before I gave it away -- with the dd running I got lockups while logging in on another VTY, logging in via kdm and finally just switching back to the X display from the console. The dd completed just fine if I didn't touch anything else while it was running. Anyone else seeing similar behaviour, or have suggestions for diagnosing and fixing this problem? I might pull the SB Live! card (these were often cited as an accomplice in the earlier VIA 686 problems) and the not-quite-supported Advansys SCSI card (see PR kern/34306). Can't really remove anything else without making the machine useless, although I could swap the video card and NIC from another box. Upgrading to the latest -STABLE and double-checking the cooling system are probably good moves as well. Thanks in advance for any ideas -- this is driving me nuts.
