I'm going to test this one. I'm randomly seeing my ASUS 1005HA
hanging after I replug the network cable. I noticed that the
driver from the Atheros site doesn't have the issue at all. I
spent a week-end trying to eliminate almost all of the diffs
between the two drivers to try to spot the faulty code chunk,
until I realized that I went past the failure point without
noticing in time because the issue was too much random :-(

Clearly a non-bisectable issue. But with just this fix, I'll
be able to tell if the problem is definitely over.

Regards,
Willy
