This patch fixes this by moving the enabling & disabling of the TCO_EN bit in the SMI_EN register into the start and stop code. Signed-off-by: Wim Van Sebroeck makes CPU fan spin with full speed and causes hald-addon-acpi to take 100% of CPU time on Toshiba Portege R500 with openSUSE 11.0 user space. This starts as soon as hal starts or thereabouts and never ends, which makes the current mainline unusable on that box. Thanks, Rafael
