This is really off on a tangent, but I thought I'd mention it on the off-chance that it fit your problem. Recently there have been grumblings about heat problems with certain nvidia chipsets on consumer boards. Apparently, there is some process issue, if you believe trade rags like theinquirer.net etc. Apparently there is some issue with heat damage over time. Consumer motherboards with passive cooled (no fan) heat pipes etc seem to be particularly vulnerable. I use the word "apparently" because it is far from a verified fact. However, I've got two motherboards, one running freebsd, one running windows, with nvidia chipsets. Both used to be fine with onboard IDE activity. Both now use raid controllers so the IDE interfaces have been idle for a good year or so. Something came up and I had to use the IDE interfaces for a lot of data transfer. Suddenly, both machines are flakey. The windows machine blue screens under load. My freebsd box just "turns off" (motherboard appears to power off, but the power supply is on still). The same happens when I use a linux boot disk, so I know its not FreeBSD's fault. The common factor seems to be that the motherboards are now about a year and a half old. They both have the same nvidia south bridge that theinquirer.net was trashing. Both used to work fine, now have problems with IDE. and now I recalled the article and started wondering... Do you, by any wildly remote chance, have an nvidia based motherboard? I believe the fault I'm seeing is the system asserting a fatal error by doing a HT ECC flood to halt everything. -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com; KI6FJV "All of this is for nothing if we don't go to the stars" - JMS/B5 "If Java had true garbage collection, most programs would delete themselves upon execution." -- Robert Sewell
