we're using this hp g1 thing primarily for torrent seeding and
gnuMotion...  so it is consistently getting ~5mb/s and pushing out 300kb/s.

the explanation on #60 might explain why this recipe is somewhat stable --
its always active.

i also havnt updated the bios - i wont have physical access for a few
months - but since others are saying it makes no diff ... think i wont
bother

- uptime/ 48 days
- RX/ 18tb
- TX/ 4tb
- 2 tg3 hangs ... and it restarted the driver on its own
