Running sensors shows this: # sensors atk0110-acpi-0 Adapter: ACPI interface Vcore Voltage: +1.42 V (min = +1.45 V, max = +1.75 V) +3.3 Voltage: +1.68 V (min = +3.00 V, max = +3.60 V) +5.0 Voltage: +1.62 V (min = +4.50 V, max = +5.50 V) +12.0 Voltage: +11.98 V (min = +11.20 V, max = +13.20 V) CPU FAN Speed: 56250 RPM (min = 0 RPM) CHASSIS FAN Speed: 0 RPM (min = 0 RPM) POWER FAN Speed: 0 RPM (min = 0 RPM) CPU Temperature: +62.0°C (high = +90.0°C, crit = +125.0°C) MB Temperature: +49.0°C (high = +70.0°C, crit = +125.0°C) Power Temperature: +24.0°C (high = +80.0°C, crit = +125.0°C) The first thing that jumps out at me is that I think I need a new PSU! How is this machine even running if 3 of the 4 voltages are low? The second thing is that the temps are just fine. So why do I keep getting these messages in the logs? Perhaps because the power rails are low? The chassis and power fans are 2 wire so no data. lshw dumps a lot of information. Anything in particular you are looking for? I think I have solved my lockup problem. I'll write a separate post about that. Thanks, Steve -- Changing lives one card at a time http://www.send1cardnow.com
