Unfortunately, it results in a lot of error print and phy tx errors that 
has been reported by others. I think the two are related, but I have not 
root caused it yet. Your laptop may be usable now, but wireless 
performance is probably bad.

Too bad I can not reproduce the issue over here. Are you willing to test 
some patches when I got a better grasp on the issue?

Regards,
Arend
