Hi David,

Try using the BIOS reset jumper on the motherboard to cause the CMOS to
clear on the MoBo (do this while the MoBo is OFF) then put the jumper back
to the normal position and power up the PC.  You should find instructions
for this in your MoBo manual (which you carefully kept in case you needed
it... ;-) ... do follow them carefully.

Hopefully this will clear the problem and allow you to boot cleanly.  Then
you can start to track down exactly where it came from.

Okay, but it maybe an issue later.  I'm asking the silly preliminary
stuff, somebody else will chime in, we hope :)

This is where we get concerned, something has upset the BIOS?

Can you try clearing the BIOS, don't run lm_sensors, but take a look
at the ACPI in dmesg and /sys area, newer BIOS now report hardware
monitoring through ACPI, which is a different ballgame.  There was
info about ACPI hw monitoring very recently either on this list or

Sorry cannot be more helpful.  Out of cluebats today :(
