1) because I didn't know what the exact bug was and how to work around it :)
2) without power management, the battery use is not good, but yes not
good is better than laptop crashing :)

That said, if it's only affecting wired ethernet, I can also unload the
igc module until I actually need wired ethernet, which is sometimes but
not often.

Thanks for your suggestion
Marc
