The 'microuptime() went backwards' happened to me also lately, week or so ago. Tyan mobo with GX chipset, power management disabled completely in the BIOS, no apm in kernel. Two PIII-550, one 20GB IBM disk (ATA). Same symptoms as above, heavy disk I/O, I was stress-testing the machine, except the machine hung for some unknown reason: I was able to switch vty's and ping the machine but not login, no disk I/O. I'm waiting for two 36GB IBM SCSI disks, which should arrive soon, then the next round without ATA is what I'm planning. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
