Intel 82573L ethernet: gigabit stopped working, 100Mb/s OK

[no_hope]

All of a sudden my ThinkPad's Intel 82573L Ethernet card stopped working at 1000Mb/s.

Some packets seem to get through, but it's very slow (ssh lags) and ethtool reports CRC errors on received packets.

Lights on the switch's port where laptop is connected blink at high rate, indicating activity even when it's not doing anything. In comparison, my desktop's switch port doesn't blink. Both laptop and desktop run gentoo with very similar setups.

The Ethernet card works just fine at 100Mb/s.

Tried removing all 100Mb/s devices from the switch, leaving only 1000Mb/s. Didn't help.

Any ideas?

My first instinct would be a bad cable.

Try replacing it, and see what happens.

Or a bad port on the switch.

Tried using my desktop's cable and port (which work) with no luck.
