Q: what does *** after Version table: mean?

With respect to e1000e-3.8.7, I guess now it's time to wait and see if there's another bad_shutdown or bad_boot and if they leave any trace
Maybe the additons to /etc/default/acpi-support have some effect?

---
Edit:
Last night I realised that the e1000e driver module now put in use by the 5.10 kernel upgrade was most probably the current one ie: e1000e-3.8.7.
But I had not applied the five patches, so that's done now.

Thanks for your input.

Yes.
I do have that in my /etc/apt/sources.list.
Must be a question of package priorities.

Will have to specifically install that: apt install nvidia-legacy-340xx-kernel-dkms/stable-backports
I'll get it done and report back.

Thanks for your input.

Did you try nvidia drivers from backports / non-free?
See: https://pkginfo.devuan.org/cgi-bin/pack … 10~bpo10+1

And there are other packages for that from backports/non-free. That seems to be supported by kernel 5.10.

Any idea why it would not shut down properly in my box?
How can I troubleshoot that?

That's what I am already doing, remember?

First at /etc/rc.local ...

groucho@devuan:~$ cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other

/usr/local/bin/acpi_wakeups.sh

# to disable wol via ethtool at boot
# does not survire reboot that's why it is here
/sbin/ethtool -s eth0 wol d
groucho@devuan:~$

... and just in case some #%&?¡ whatever decides differently, with my shutdown script:

groucho@devuan:~$ cat /usr/bin/shutdown.sh
#!/bin/sh
# added to shutdown directly - no shutdown helper 
# options added to troubleshoot nic related bad shutdown 
PATH=/sbin:/bin:/usr/sbin:/usr/bin:

# sync
# disable onboard eth wol
# shutdown system directly 
sync && sudo ethtool -s eth0 wol d && sudo shutdown -h now

I've come across a couple of pages related to PM and /etc/default/acpi-support.
As acpi-support seesm to have been deprecated long ago, I had to look around for oldish pages or get systemd only hits.

I added the links to the file so as to remember where it all came from:

groucho@devuan:~$ cat /etc/default/acpi-support

With respect to the >5.5 kernel upgrade:
I installed 5.10 but there are no drivers for my Nvidia cards.
It seems that the nvidia-340xx-legacy driver used by my perfectly working Nvidia Quadro FX 580 cards has fallen out of favour with the powers that be.
And from what I have read, caused a lot of noise.

I think Manjaro and Ubuntu have put out patches, I expect Debian/Devuan will follow suit. (?)
So I'll have to wait.

I'm not going to give up my 580's or use nouveau, unless it improves.
They still have a few years left in them.

I'll apply patch 1005 and report back with whatever results I get.

Thank you very much for your help.

Best,

Yes, here it shuts down properly...

Last patch:
https://geki.selfhost.eu/hacks/1005-e10 … tach.patch

On a second thought, if your system entered sleep and e1000e called the pm_freeze function things could be corrupted, indeed. And next shutdown and start may go boom?! Another wild guess.

And for WoL, too tricky to patch actually. I just recommend you to set the ethtool disable WoL command early in boot process and not before shutdown. e heh. Just because we want it to stay put from the beginning.

And yes, with this I am out of thoughts....

I have found no other record of e1000e activity on a bad_sutdown.

I don't know.
There's the issue of not being able to disable sleep state in the BIOS.
And that being set to S3.

The thing would be to avoid the system from picking it up and overriding what the BIOS says.
ie: the proper way to do things

Sorry to hear that, but I understand.
You've done more than enough already. 8^)
And no one else has made any suggestions.

Maybe not patch WoL as that seems to be taken care of vie ethtool and boot and shutdown.

BTW: you have this in your system?

     # Make it possible to not shut down network interfaces,
        # needed to use wake-on-lan
        netdown="-i"
        if [ "$NETDOWN" = "no" ]; then
                netdown=""
        fi

        log_action_msg "Will now halt"
        read -p "Press enter to halt ($netdown $poweroff $hddown)" reply     <--- this line added
        halt -d -f $netdown $poweroff $hddown
}

Does it shut down properly?

Thanks for your input.

You got that PCI REMOVE prints once out of dmesg? A normal shutdown would not enter S3? Though, I am out with that. :-D

I patch WOL and PM FREEZE detach thingie and that's it from me. :-)

Screen was frozen, needed a hard shudown.
dmesg0 does not show anything strange.

I could reproduce the whole thing but how to get what dmesg recorded, if anything at all?

Thanks in advance,

That's what I think is the question here.
I think the answer is in the U24's BIOS.

Remember that I have not been able to disable ME "Firmware Power Control" and "Host Sleep States" in BIOS.
It is set to S3, I can set it back to S0 but I cannot disable it.

Right.

groucho@devuan:~$ cat /etc/default/halt
# Default behaviour of shutdown -h / halt. Set to "halt" or "poweroff".
HALT=poweroff
NETDOWN=no
groucho@devuan:~$

I'll take your word for it.
Don't have a clue as to what is strange here ...

That is supposed to be the tool to use.
When the HW or the driver does not undo it behind your back.

Thanks for sharing.
But it's you doing the patching. 8^)

geki wrote:

Right.
Would be like disabling it in the BIOS, which for whatever reason cannot be done without screwing up everything.

I discovered an old Sun Microsystems thread.
Had to find a catched copy.

Seems that this was a hard cookie from the very start of the Sun Ultra 24's market debut:

If I understand correctly, it will shut down on Enter.

Never got that far ...

Here's the part that I edited:

        # Make it possible to not shut down network interfaces,
        # needed to use wake-on-lan
        netdown="-i"
        if [ "$NETDOWN" = "no" ]; then
                netdown=""

        read -p "Press enter to halt ($netdown $poweroff $hddown)" reply     <--- just this line
        halt -d -f $netdown $poweroff $hddown
}

On shutdown, the box froze at this point:

Good sign is that there were no fans blowing.
Only way out was a hard shutdown.
REISUB did not work or maybe it was that I could not type and hold Alt+SysRq at the same time?

This happens whether I shut down with my script or with sudo shutdown -h now from a terminal.

Thanks in advance.

Since you got no pm tooling, I wonder who enters S3. Only one visible for now is /sbin/halt with its unsetted NETDOWN. If not that, it must be the kernel on its own, then?!

Anyone here knows about sleep state handling?

Well, you want to put NETDOWN=no into /etc/default/halt to disable WoL handling of /sbin/halt. Quite strange parameter to what it is doing in the end.

Though, you still want to disable WoL via ethtool. The more disabling, the better.

And yes, we want to disable WoL, too. We can get a patch to forcefully disable WoL by module parameter. I already spotted the flag in code, which activates WoL. We can, hypothetically for now, reset that in src/param.c, e heh. But even with that hypothetical patch, We want to disable WoL from /sbin/halt. And ethtool will be superfluous, then.
