(In reply to comment #39)
Thank you. I've done all that, and although the results don't seem very
helpful I hope they have some meaning!
1. "ethtool eth0" returns the following in both 12.3 and parted magic:
Supports Wake-on: pumbg
Wake-on: g
I confirm that "ethtool -s eth0 wol d" under 12.3 does change the wol setting
from "g" to "d". But it makes no difference to the shutdown behaviour - I
still get a reboot from "shutdown -h now".
[Comment: From previous experience with another machine and an earlier version
of openSUSE and using an add-in PCI ethernet card, I remember that I had to
alter one of the shutdown scripts to ensure that the desired wol setting
survived the shutdown process itself. But that was under sysvinit, and I've no
idea whether a similar kind of thing might apply under systemd]
2. I haven't attached the output files for "ethregs" because it returns only
the one identical line in each case, including 12.3 with the standard kernel,
12.3 with the parted kernel, and parted magic itself under chroot. The line is
simply:
"unknown device id=0x153b"
[General comment: Strictly as an amateur in these things I'd thought the fact
that, since the peripheral on/off wol settings for the embedded ethernet
controller in the BIOS have no effect at all on the reboot-from-shutdown
behaviour, but that the problem seems to turn exclusively on the mainboard
"Wake on LAN from S4/S5" switch setting, there's a pretty strong suggestion
that the cause lies somewhere other than in the eth0 settings themselves.]
Thank you again for listening.
Robin
