Hi all,

the above error message occurs when booting the upgraded system on my lenovo thinkpad T410i and hangs the boot for about 10 - 20 seconds.
Any idea how to solve this?

First check to see if the directory structure under /sys does exist, if not try and create it.

As root

mkdir -p /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.3/1-1.3:1.0/power/level

Hope that helps.

No,
i cant create a file there, cause it leads to an “No such file or directory”

I just did a reinstall. Former it was a upgrade via DVD, so i choose to fresh install it. Same problem.
