These circumstances are rather surprising: the problem happens when the machine is rebooted, or when it is suspended and resumed, while AC-powered in both cases. I think that the BIOS does something (God knows what) with the timer, leaving it in some state the FreeBSD's clock initialization routines don't deal with adequately. Unfortunately, I have no info about the PC's timers, so I would be grateful for some help. If someone has any idea about what things could I try, I am willing to test them (I have both 3.4-RELEASE and 4.0-RELEASE installed on the laptop). Also, pointers to docs (or recommendations of books about PC hardware) will be welcome.
