Thanks, UDENIX, so feel compeled now to report this bug, even though I bet you
were just trolling me.

OS: 7.5 -current except it's like 1 week old current
HW: Lenovo Thinkpad T400
BIOS: A few years old Libreboot

So, the bug acts like this:
I have lidaction set to hibernation.
Every now and then the hibernation will never finish, until I plug OUT my wifi
adapter which is an urwtn device.

Then the hibernation completes in a few minutes so I'm guessing the
hibernation hangs around the beginning of hibernation because the entire
hibernation duration usually lasts about that amount of time.

No idea why that is, perhaps hibernation is waiting for WiFi to stop WiFi-ying,
but it never does :/
I don't think that I had an program that was actively using the internet, if it
matters.

It might be a BIOS problem? No idea.
