Kai-Heng, the bug seems to be gone on my system with your newest kernel
in #63 and I don't experience any regression so far. Thanks for your
work!

For me the update makes things worse instead of better.
Before installing the updated kernel, it only happened from time to time
that the ethernet driver had locked up after suspend (and thus needed to
be reseted by removing and reloading the module via modprobe).

I have to correct myself a bit: Network coming up correctly after
suspend only works from time to time. On the cases where it's not
working, the driver still has to be reloaded.

I did that, with net-next directly it seems that everything is working again at
least as good as in 4.15.0-23 (Network card comes up at boot, and also after

So hopefully this got fixed in net-next.

I did check it again yesterday and today using 'systemctl suspend'. The

Yes, the output of 'lsmod|grep alx' is indeed empty.
Since my system doesn't have wifi, I don't think anything WPA related
could be the cause. I ran the commands anyway:
sudo wpa_cli suspend ; sudo systemctl suspend; sudo wpa_cli resume
and it has no positive impact. The output of wpa_cli is
Ok, then I'll test those hooks, it may take a few days before I can give
a definitive feedback because it will need quite a few suspend-resume
cycles to validate if one of the hooks really makes the problem go away.

Thanks for the hint to try more than one hook at once, that's really
useful!
I'm done with the testing faster than I thought, because unfortunately
none of the hooks makes the bug go away. I even tested applying all five
of them together, but no success.
The only thing notable is, that /bin/sh sp

Hello Martin,
I think I have found the real cause of the bug: It seems to always
happen when the wol flag is set to 'ug' (instead of 'g' or 'd'). I made
a few reboots and checked the wol value with 'ethtool eth0' and it was
always set to 'ug' by default after system startup (I don't know if this

The lasted upstream kernel I could test was 4.2.3, because with 4.3 the
compilation and installation of the Nvidia kernel module fails, and I
can only test with the propritary Nvidia driver because suspend doesn't
work properly with Nouveau on my card.
** Tags added: kernel-bug-exists-upstream ker
Disregard my last comment - I did a test anyway with 4.3-rc4 and Nouveau
and supending with Nouveau worked at least one time so I could reproduce
and confirm the bug for 4.3-rc4.
