Lots more --mark-- lines That's all that syslog logs show about the crash/reboot. The hardware is a Gigabyte VEML board with on-board everything, a 1200 MHz Tualitin Celeron CPU and 2x128 Mb SDRAM in a 1U rack case. There's a 20 GB WD drive and an Asus CDROM and a FDD. Where else can I look for more info? There is nothing on screen after the reboot of course. I could disable ACPI and see if that's the problem, but the board had been running fine for months in another case/PSU. PSU faults? How best to determine that? -- C.
