Hi all,
I've been experiencing complete system lockups on my Athlon box (Abit KG-7
mobo, XP 1800+, 512MB Crucial ECC DDR RAM). 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.
Scott
