Re: [PATCH] x86_64: fix problems due to use of "outb" to port 80on some AMD64x2 laptops, etc.

This change seems rather unlikely for 2.6.24 at this point (high risk),
but could be good for 2.6.25.

One thing it should probably have for the early going,
is a simple way to turn it on/off at boot time,
so that we don't have people "stuck" unable to run
the test kernels should something weird happen.

Alan / David / Ingo,

What do you think of the idea of a *temporary* boot flag for this,
something like port80=on/off (pick a suitable name) ?

Cheers
