[Bug 619343] Re: High CPU on events/0 or 1 and on board networkcard non functional

[David Holmer]

I believe I found a solution to this problem:

You must fully power OFF your computer to clear this error state.
Reboot/restart and sleep are NOT sufficient.

I was able to get my Ethernet port working normally again by shutting
down, unplugging AC adapter, and removing battery for a minute. When I
brought the machine back up after this Ethernet port was working
normally again and has been for some time now.

Before hitting upon this solution I was able to guess that this was some
kind of hardware bug because my Ethernet port still didn't work even if
I rebooted into Windows Vista (i.e. it was specific to Ubuntu or Linux).

I suspect that all the people above who reported switching to a
different kernel solving their problem may have done a shutdown and that
is what "fixed" their issue rather than the different kernel itself.

Hope this helps anyone else coming here with the same problem.
