FYI, While it is slightly off-topic of the (I agree, real) technical issue here, note that polling is not "normal" on ACPI systems. [1] was on SuSE Linux 10.0, which on their own decided to over-ride the kernel and enable thermal zone polling by default. This turned out to be a bad idea because it exposed BIOS bugs in ACPI thermal zones that were never exposed on other operating systems - evidently because the other operating systems never poll thermal zones, they are entirely event driven. cheers, Len Brown, Intel Open Source Technology Center > Luca > [1] http://www.lm-sensors.org/ticket/2072 and: > http://thread.gmane.org/gmane.linux.drivers.sensors/12359
