I just wanted to add a comment to this thread without having to subscribe to lkml. The problem I'm seeing is the one described, but it seems to bring the whole device down with it hard. Even a reboot doesn't restore the link and gPXE, Linux 2.6.29.1 or older versions (tested with a 2.6.27 version) can't find the link any more even after a power cycle restart. The only way I can find to bring it up again is to boot into windows (I just installed an old copy of XP to a spare partition just for this) and when the green light starts to flash again, I can reboot and netboot with gPXE or use the interface in Linux again.

The reason I'm commenting is that the patch seems to my context-less, untrained eye, to be restoring the link on resume/init, but that won't help those who are netbooting with gPXE, or rebooting into older versions of Linux.

This is on an MCP55 motherboard.
