Please send a bug report using the template froom sendbug -P run as root so that it includes the ACPI tables, pcidump output, etc. Save one from a "slow" boot and one from a "fast" boot, if there's a difference in pcidump / acpi tables / dmesg then send *both* and say which is which. Also "vmstat -i" from slow/fast might give a clue.
