[Ac] hdparm hangs often during starting (udev issue?)

[Tomasz Wittner]

Hello,

Nearly every two booting I'm forced to press reset button on my workstation 
(or sometimes is possible Alt+PrintScreen+S/B) - starting hangs during hdparm 
invokation. Because hdparm is called right after starting udev I suspect that 
udev (v. 079) doesn't finish its job and hdparm maybe hangs because 
of "queued kernel/udev events"[1] are not handled yet.
Newer udev (v. 104) has binary called udevsettle which is used in start_udev 
(PLD Th) or /etc/init.d/udev (Debian unstable f.e.) scripts. As is said in 
[1]man udevsettle is used for delaying script execution until queued 
kernel/udev events are handled.
