Hi,

  I have a spare hard disk I don't touch the most of the time. Due to a
strange reason, a change uevent is triggered some random time of the day
(like 4 or more times) and then, of course, udev apply the rules, being
one of them a rule which runs vol_id which then wakes up my spinned-down
hard disk (debugged with echoing a 1 to /proc/sys/vm/block_dump and
udevadm monitor).

  Well, what i want to know is if it's possible to know why the kernel
is triggering the uevent in the first place. Grepping the documentation
of the kernel I don't see anything about it. I know I can just comment
the watch line in /lib/udev/rules.d/60-persistent-storage.rules but I
wanted to know more.

  I'm using Archlinux which currently uses kernel 2.6.28.8 and udev 140.

Thanks in advance.
