I've just booted kernel 2.6.26 (Debian lenny) on my new Thinkpad X300.
Things seem working OK so far except I can't get gigabit ethernet.
Output from ethtool says:

Settings for eth0:

As you can see both the hardware and the link support full duplex
1000baseT, but I'm getting only 100Mb/s (confirmed by lights on switch).

I tried

  sudo ifconfig eth0 media 1000baseT

but that media type isn't even recognized.

I also tried

  sudo ethtool -s eth0 speed 1000

but this seems to have broken the ethernet port entirely
(although a reboot brings it back).

Does anybody have any ideas?

P.S. After all this messaing around, it now negotiates down to 10Mb/s.
Booting 2.6.24 seems to get back to 100Mb/s.

I had a simmilar problem once. Turned out my Linksys Gigabit Switches didn´t quite like to work with Intel and Realtek NICs. Only Marvel could get GiBit speed. All else negotiated at 100 and 10.
I tried D-Link Switches an had GiBit on all NICs again.
