Same with FC3. Also tested with other kernels... Probably simething in ACPI .... Yup, indeed. Maybe the IBM Power Management driver for Windowz takes care of that under windoze. In that case, the cpu fan is software controlled and not controlled by the BIOS or some hardware temperature thingy. If the fan is controlled via software, then this is a dead issue. IBM never releases any hardware information for their ThinkPads. One such example is the lm_sensors util that kills ThinkPads, IBM never helped solve the problem. An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you. The ibm-acpi project has managed to control the CPU fan, thus making it possible to turn off and on the fan based on the CPU temperature. |
