Public bug reported:
Binary package hint: udev
Recently very often I see udev stays with CPU usage between 10 and 15% on my
Intel Core 2 Duo P8400 2,26Ghz through about one minute, then it does nothing
through another minute and start this cycle again. What can cause such behavior
? It started happen last time, I have no idea if it's caused by upgrade to
karmic(kernel 2.6.31.x) or recent udev upgrades from apt.
I guess there is to much events from my SATA controller:
nu...@novopad:~$ time udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
