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:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbag
Wake-on: g
Current message level: 0x00000001 (1)
Link detected: yes
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.
