Message-ID: <20120212075605.7922d4d00adb817577249514@gmail.com> (raw)
not sure if this ubuntu's issue with the development branch of there software,
but suspending with this machine and waking-up with
good quality wireless is not consistent.
I have noticed this message in the syslog(but am unsure if its related to the suspend issues
since I was getting other traces with other modules)
