Investigating the x2apic report in dmesg :-

[ 0.078322] DMAR-IR: x2apic is disabled because BIOS sets x2apic opt out bit.
[ 0.078323] DMAR-IR: Use 'intremap=no_x2apic_optout' to override the BIOS setting.

I added intremap=no_x2apic_optout to GRUB_CMDLINE_LINUX_DEFAULT
in /etc/default/grub and ran update-grub.

After a reboot, dmesg reports :-

Looking further at the Realtek firmware.

The download link at Realtek is for the driver r8152, which we already have, rather than
the firmware. I found this firmware at Google Chromium :-

https://chromium.googlesource.com/chrom … 3/rtl_nic/

I downloaded the tgz file and unpacked it and then copied
rtl8153a-2.fw to /lib/firmware/rtl/

I rebooted and now dmesg has no lines in red and reports :-

dmesg|grep 8153

[ 1.990237] usb 2-3: New USB device found, idVendor=0bda, idProduct=8153, bcdDevice=30.00

I had a look at the DMAR errors and found this :-

https://bugzilla.kernel.org/show_bug.cgi?id=202723

which suggests

intel_iommu=igfx_off

This didn't stop the errors but

intel_iommu=off

does now stop all of the DMAR errors in dmesg.
I added this in /etc/default/grub to

GRUB_CMDLINE_LINUX_DEFAULT="earlyprintk=vga,keep net.ifnames=0 init=/sbin/openrc-init intel_iommu=off"
and then ran update-grub.
There is documentation about this at :-

So it seems that several of the errors only come with the newer kernel.

Checking up on the regulatory db, I found this :-
https://www.linuxquestions.org/question … 175622954/

crda is not installed so I installed it.
I can now see :-

after a reboot, dmesg now reports

Checking on the Realtek firmware I found this :-

https://unix.stackexchange.com/question … 68g-3-fw-2

I installed firmware-realtek. This seems to have installed some likely looking files,
although not the exact numbered one reported in the error.

https://askubuntu.com/questions/898128/ … untu-16-10

suggests getting it from Realtek
https://www.realtek.com/en/component/zo … 0-software

which seems to want my email address.

https://www.realtek.com/en/products/com … em/rtl8153

https://www.pcsuggest.com/install-rtl8153-driver-linux/

suggests that the generic cdc_ether driver is often used.

lsmod| grep ether

cdc_ether 24576 0
usbnet 53248 1 cdc_ether
usbcore 315392 8 xhci_hcd,usbnet,usbhid,uvcvideo,btusb,xhci_pci,cdc_ether,r8152

which also mentions the r8152 module.

The wired ether seems to work ok with the error messages in dmesg.

https://wiki.debian.org/Firmware

doesn't seem to find this driver.

Re: quick note on chimaera installs (attn: fsmithred)

dummy@example.com (Geoff 42) — Wed, 10 Jun 2020 12:55:10 +0000

I did a fresh netinstall of Beowulf on a Xen VM (Dom0).
I had installed claws-mail, but that was about all and
then upgraded it to Chimaera. This went with no problems.

So I then tried upgrading my laptop. I can't remember
how it got to Beowulf, but probably started with Debian
and migrated via Jessie, ASCII to Beowulf.

Trying to upgrade with apt suggested some problems, so
I used aptitude, which suggested a way round the incompatibilities.
I accepted these and let it proceed. It had almost finished but
ended with :-

Error: Sub-process /usr/bin/dpkg returned an error code (1)

I ran aptitude full-upgrade again and it removed fdisk.
A further run ended without doing anything.

I then then tried to reboot, although I am running OpenRC
and have replaced SysV init with openrc-init. The reboot
failed to shut down, so I did sync;sync and hit the power
button. After this it booted ok and I have since been
able to shutdown and to reboot ok.

I am running Postgresql. This needs some action on upgrades,
but this failed as version 12 had failed to install! All I
needed to do was install postgresql v12 (I used Synaptic).
Then I could do the upgrade from 11 to 12 and then remove v11.

I have spotted some messages in red from dmesg. These seem
to suggest problems with firmware. I wonder whether these
may be related to the new kernel. Linux version 5.6.0-2-amd64
Most of these messages seem to involve firmware or DMAR.

I guess that the regulatory.db is related to the wi-fi

I must try booting with an older kernel to check that these
messages do not occur there.

I had no problems with polkit.

No problem with polkit stuff here. I now see that -backend is gone. The upgrade from fresh clean-installed beowulf seemed to take it in stride.

I wonder if it wasn't something left over from ascii... I have a beowulf that I upgraded from ascii ages ago - next time I'm over there I'm gonna see what polkit stuff it uses. It's so old that I can't possibly recall all the wrestling I did with it over the months when beowulf was pretty rough. Some of the workarounds for weird circular dependency dilemmas were like magic spells - had to do everything in just the right order. I have mostly used MATE for years now, probably since Debian Wheezy, so pretty much my entire experience with Devuan has been MATE.

Re: quick note on chimaera installs (attn: fsmithred)

dummy@example.com (fsmithred) — Sun, 07 Jun 2020 17:22:43 +0000

Thanks. I just finished a dist-upgrade from beowulf to chimaera on a laptop. Had some trouble with conflicts and had to remove libpolkit-backend-1-0 manually (it no longer exists) and upgrade one of the libpolkit packages manually. Also used a combination of apt and aptitude to get through it. I didn't take notes, so I don't have instructions for anyone.

This was with xfce. I think it was a refracta-ascii that I upgraded to beowulf a year ago. Now it's chimaera and seems to be working ok.

quick note on chimaera installs (attn: fsmithred)

dummy@example.com (sgage) — Sun, 07 Jun 2020 16:31:09 +0000

Here are some notes on two recent installations of Chimaera, pretty much directed to fsmithred. I just thought this would be easier than #devuan...

Yesterday I installed your latest 'experimental' live cd version. It went very smoothly.

I confess that openbox is a bit minimalistic for me, so I installed MATE (and slim), and the rest of my usual stuff, no problems. It's all working just fine.

One seeming omission: it seems that you didn't have any ssl certs installed -
hexchat complained loudly, as did a couple of other programs I use.

I did some poking around, and installed ca-certificates, ca-certificate-java, and python3-certifi - all was well.

---

Today I made a fresh install of beowulf/MATE from the netinst iso and then dist-upgraded to chimaera. All I can really say is that, again, it went very smoothly. I installed my usual programs and tweaked the look&feel a bit, and it really seems quite solid - I'm using it right now to post this.

---

Let me know if there are any specific things you'd like me to test, and I'll try to accomodate...
