I just got a similar crash: unexpected machine check: mces = 0x1 vector = 0x670 param = 0xfffffc0000004e10 pc = 0xfffffc00004069bc ra = 0xfffffc00004069b4 curproc = 0xfffffc001f169200 pid = 23, comm = intr: sym1 panic: machine check cpuid = 1; boot() called on cpu#1 syncing disks, buffers remaining... panic: bdwrite: buffer is not busy cpuid = 1; boot() called on cpu#1 Uptime: 19h27m51s It's an Alphaserver 4100, dual 5/300 with 512 MB RAM and one power supply, running 5.0-RC3 (kernel is GENERIC plus the line from ccd(4)). I had been trying to compile a few large things from the ports collection, Beonex for example, and all the compilations had finished so the main task was "dd if=zero of=da2" which had been running from /dev since a few minutes after boot (only a 4 GB disk--I wonder why it's so slow). $ strings /tmp/4100-20030113-cu4.log | grep degrees System temperature is 23 degrees C System temperature is 23 degrees C System temperature is 23 degrees C System temperature is 23 degrees C System temperature is 24 degrees C I was sitting next to it when it crashed, and I would have noticed if the fans had stopped. From earlier logs, I see that the temperature has varied between 21 and 27 Celsius. I don't know what it is now, but it feels warmish when I'm wearing just a tee shirt. There's a fan that constantly blows air into the room, which points toward the back of the computer. Should I run the air conditioner more often? -- Trevor Johnson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
