Tyan motherboard with Intel GX chipset, 256MB of memory, one 20GB IBM UDMA66 disk, but running at UDMA33. All power management disabled completely in the BIOS. I was doing massive parallel compiling of GENERIC kernels. Let the machine doing this overnight and on the morning the console had about 20 'microuptime() went backwards' messages, I was able to switch vty's but not login, machine responded to pings, no disk activity. I'm using ata driver and only one unusual kernel option HZ=1000. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
