Hi,
I have recently upgrade my kernel, and found that Intel AMT support is
not working anymore as expected. I have configured IAMT so that is
always available, even when the machine is off ("Desktop: ON in S0, S3,
S4-5").
On recent kernels, IAMT support does not work after the machine has
been powered-off. Even worse, it also goes into this state when I try
to reboot it.
I have done a bisect and got this commit:

| e1000e: WoL does not work on 82577/82578 with manageability enabled
|
| With manageability (Intel AMT) enabled via BIOS, PHY wakeup does not get
| configured on newer parts which use PHY wakeup vs. MAC wakeup which causes
| WoL to not work. The driver should configure PHY wakeup whether or not
| manageability is enabled.

I have tried to revert it on recent kernels (2.6.34), and IAMT is then
working as expected. My machine is using a Gigabyte EQ45M-S2 motherboard
with an 82567LM-3 ethernet chip (8086:10de), that is a different model
than the one of the original problem.
I do wonder if the changes in the patch should not only be done on some
chip models, and I will appreciate any help in fixing this issue.
Thanks,
Aurelien

Just a short mail to say this problem is still present in 2.6.38-rc2.
The same solution still applies, that is reverting the above commit.
Note that reverting the first hunk only is enough to get it working
again.
