On my Dell M101z everything in Ubuntu 12.04 works perfectly out of the box with one minor exception:

After several sleep cycles (somewhere between three and ten), after waking the machine from sleep it won't reconnect to my wifi.

When this happens, a reboot allows it to connect automatically every time.

I've noticed when it wakes from sleep that there's some logging into that appears very briefly before the desktop is redrawn, but it happens so quickly I've been unable to make out what it says.

What log might I look in to review that info?

Any other tips for diagnosing/resolving this?

Thanks in advance for your help -
