Started at 22 C and ran for three minutes in CLI. Took it into X and ran top -- 1.7% CPU and 22 C for another couple of minutes. Started a little looping Tcl script (poorly optimized for niceness) that took it to 33% CPU -- went to 68 C in 46 sec. Stayed there the rest of the time. What is the likelihood that the BIOS as reported through cat /proc/acpi/thermal_zone/THRM/temperature is lying about the temp? They have accepted it back in for more diagnosis on the original dime. -- Lan Barnes SCM Analyst Linux Guy Tcl/Tk Enthusiast Biodiesel Brewer -- [EMAIL PROTECTED] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
