hm, on a T60, after suspend/resume, i get an e1000 timeout:

e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang
Tx Queue <0>
TDH <ec>
TDT <ec>
next_to_use <ec>
next_to_clean <82>
buffer_info[next_to_clean]
time_stamp <fffcc3db>
next_to_watch <82>
jiffies <fffd5da0>
next_to_watch.status <1>

it works fine after that reset. The e1000 driver didnt do this before
after resume the network was always available immediately. So this
appears to be a relatively new regression (post-rc3 or so). high-res
timers was disabled.
