Not sure > about the fans... My fans seemed to work ok most of the time before, it was the battery status which hung, and the speedstep would never go to full speed. Everything is happy with Ubuntu's kernel 2.6.17-10 and when unloading psmouse as part of the shutdown and reboot scripts. I did dig though psmouse a little, but being a non-expert, couldn't see anything odd. It could be the synaptics driver part I guess, as most people have laptops. It could be that psmouse keeps a serial driver of some sort alive, or a bus active. Perhaps it is still receiving and processing interrupts as the bios tries to reboot? Does someone need to open a kernel bug for this, and where should it go?
