Hi!

Perhaps you should get regressions@xxxxxxxxxx alias, or something like that?

As always: Are you aware of any other regressions? Then please let me
know. For details see http://bit.ly/lnxregtrackid And please tell me if
there is anything in the report that shouldn't be there.

I am using wake-on-lan quite a bit, and it stopped working. I'll move
to -rc4 and test there; but if anyone already has some ideas, let me
know.

Hardware is thinkpad X220

00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network
Connection (rev 04)

I guess this is ACPI S3 suspend?

ACPI S3, right. Machine still wakes up properly when I hit a key on
USB keyboard.

OK, so my guess would be a driver issue. What driver is this, igb?

Does wake on LAN work on you, on any hardware?

Yes it does, I checked two machines earlier today, both work.

Can you enable dynamic debug in device_pm.c and send a dmesg output
with that covering a suspend-resume cycle?

82579 is e1000e
