pm-suspend does not work with networkmanager enabled

[ofosho]

I am trying to get my laptop to suspend properly, but when the networkmanager script is included in /usr/lib64/pm-utils/sleep.d suspend always fails.

Here is the dump of the log:
Initial commandline parameters: --quirk-none
Blacklisting 01grub.
Blacklisting 90clock.

Line 13 of kernel is: echo -n "mem" > /sys/power/state

I ran the code snippets from the networkmanager script to sleep/wake NM and it worked fine. Apparently when the script is run as part of the suspend sequence pm-suspend no longer has write permission to /sys/power/state? Any thoughts?

Thanks!
