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:

| commit 82776a4bcd7aa5fbcd2e6339b3ce88b727dd40ab
| Author: Bruce Allan <bruce.w.allan@intel.com>
| Date:   Fri Aug 14 14:35:33 2009 +0000
| 
|     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

I will look into this in the next couple days.
