Isn't there a Solaris acpi kernel module (tzmon) that in theory could enable (cpu / case) fans when a thermal zone is getting hot or is overheating? Are there any error or warning messages from the "tzmon" kernel module logged to /var/adm/messages? The attached dtrace script monitors the temperature for each thermal zone, as seen by the "tzmon" kernel module. Does it produce any output on your T60p? -- This message posted from opensolaris.org
