Comment 5 for bug 208103

I had somehow the same problem. But I don't think it is a pm-utils problem it is just triggered through suspend/resume.

You have a udev problem, because following in your dmesg output:

wlan0_rename

and after resume:

wmaster0

Solution:
Remove the following file it gets regenerated after the next reboot:

rm /etc/udev/rules.d/70-persistent-net.rules

Maybe you've got a long bootup delay too, this will be gone too ;)
