I'm sure I've seen a bug report regarding this before, but I've searched and have been unable to find it, and it has occurred in both Oneiric and now Precise.
On my laptop, an HP ProBook 6555b, using a Yukon Optima 88E8059, if I do not have the charger or a network cable plugged in when I power the machine on, I am unable to use the wired network port; I have to shut down the machine and plug AC or a network cable in before powering it up again.

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.
We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.
You can update to the latest development kernel by simply running the following commands in a terminal window:
sudo apt-get update
sudo apt-get upgrade
If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.
If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.
Thank you for your help, we really do appreciate it.
