Hi all,
I'm having another issue with jme and I'm not sure if it's related to
the same issue with suspend/resume, but the problem now is WoL.
Let me try to describe the problem a bit:
I put my machine to sleep in S3 and I send WoL packets from a laptop,
and the machine doesn't wake up at all, I tried inspecting packets
with tcpdump and nothing shows up in the tcpdump output.
When the machine is in working state, and I send WoL packets and I
initiate a S3, it refuses to go in sleep mode.
I tried the same in Windows (waking up from S3 via WoL) and it works there.
Does anyone have any ideas what the problem can be? I talked with Guo
and he suspects the problem is motherboard failure, I also think the
issue can be a BIOS bug since I hear so many horror stories about AMI
BIOS issues with Linux.
But it's still a mystery to me given all these conditions I mentioned.
Diego
