Hello,
The following diff is really important because on some machines
bge(4) gets detached because of ASPM. The following diff is also
in the latest snapshots but you can also compile a kernel with it.
So if you have a bge(4) please update/compile a kernel and get
back to me if it works or fails in some way.
Thank you!
