It looks like there are two problems here:
(1) Some notebooks power off and back on when restarting.
Both Linux and other OS handle that badly because they
assume power is not interrupted on reboot. The noise
emitted is relatively loud.
I'm affected by this problem, hp nx7400 + Seagate Momentus 5400.3 160gb SATA
When "drive spins down, acpi_power_off is written on the console, the
drive spins up again, and 3-4 seconds later the notebook is powered
off, leaving disk heads not parked I think.
I've not tried any new kernel or patches. I'm using stock debian Etch
kernel 2.6.18-5-686.
