Hope that you get a more useful response.... FWIW, I Had precisely these
symptoms on my Sony 2200 laptop - and can't tell you why - but it is rock
sold now. I think there were two things going on:

1. This might be a "kill" switch? Some of my problems were certainly due
to the kill switch. I finally noticed that the little wireless LEDs were
off. I had turned them off while using the windows OS - given that it is
susceptable to the wonderful new driver attacks - and had failed to turn
it on when booting up hardened Linux (which I believe is NOT susectable to
the driver buffer overflows).

2. I also suggest a step by step walk-through of the following page (check
your kernel config).

P.S. Contrary to their suggestion, I emerged the latest driver/firmware
from portage.

Newbie. (HTH; good luck.)
