Subject: e1000 driver problems

Hello,

I have laptop thinkpad T61 with 82566MM Gigabit Network Connection (rev 03)
(8086:1049). I have kernel 2.6.24-rc3. E1000E driver does not work (the card
is not detected although it is PCI-E), with E1000 driver, it works mostly OK
unless I force speed to 100Mbits. (ethtool -s eth0 autoneg off speed 100)

I got message about device hang:

and so on.
