ACPI errors at boot

English Install/Boot/Login
1

HI all, since yesterday’s update I get ACPI errors at boot. First they caused the laptop not even to start, now I can boot again but everything is very slow.
I have a Medion Akoya E15302 laptop with an AMD Ryzen 5 3500U CPU and Radeon Vega 8 graphics.
The errors I get are (starting at line 2 here):

2.454958] ACPI: Video Device [VGA] (multi-head: yes  rom: no  post: no)
2.455151] ACPI BIOS Error (bug): Could not resolve symbol \_SB.PCI0.GP17.VGA.LCD._BCM.AFN7], AE_NOT_FOUND (20200528/psargs-330)
2.455198] ACPI Error: Aborting method \_SB.PCI0.GP17.VGA.LCD._BCM due to previous error (AE_NOT_FOUND) (20200528/psparse-529)
2.455233] ACPI Error: Evaluating _BCM failed (20200528/video-357)

I also copied line 1 from the error messages cause I read on the internet it could have something to do with graphics. The graphics line is the one just before the errors happen.

I tried several USB sticks with several different Linux distro’s on them and nothing worked, making me think it is not caused by the installed distro, Tumbleweed.
I could boot the laptop from an Opensuse live CD although it was very, very slow. But at least it booted again, so I copied all my files to the network. When that had worked I rebooted into the installed version and it also booted again, also very slow.

Who can help me to get rid of these errors? If you need more info please let me know and please also tell me where and how to find it.

Thanks.

Hi
Likely the firmware issue seen with ryzen/vega setups, see here on how to roll it back: https://forums.opensuse.org/showthread.php/545773-AMDGPU-failure-after-zypper-dup-today on my laptop with the A10 APU (Dual GPU), no issues seen…

Thank you Malcom for your tip to look at the other thread.
I tried solving it with https://forums.opensuse.org/showthread.php/545773-AMDGPU-failure-after-zypper-dup-today?p=2973799#post2973799 but after rebooting I still see the errors on screen. As far as I can tell all is working so I guess I just wait till a fix will be released. Situation now is completely different than yesterday morning when I couldn’t boot at all.

Thanks again.

Hi
The same errors? If system is working, then it would probably take a BIOS update to fix…

Hi again, I have had problems again with the laptop: it did not want to boot anymore. I managed to boot it from a Tumbleweed live USB disk with extra boot parameters: ACPI=OFF and nomodeset. I then erased the disk, deleted the partition table, made a new one, made new partitions, formatted them and installed Tumbleweed. During booting I do see the errors flash on screen but laptop is working. I then downloaded a Leap ISO and booted with that from a USB disk. Same thing, still errors. So I wonder:
is Leap using the same kernel-firmware as Tumbleweed nowadays
How do the errors survive when I clean the harddrive completely? Or don’t I clean the drive completely when I delete the partition table. Is there a way to also clean the MBR or is that useless in this case?

I do love this laptop, it is really fast and quiet, but I don’t want a new laptop to have errors during boot, not even when when I don’t notice anything during working with it.

What to do now?

Try Fedora 32 Live: Fedora Workstation | The Fedora Project

Some time ago I experienced with Fedora but not everything worked so I stopped with it.
Can somebody please explain what exactly is going on here now. What can I do to make it go away. I love Tumbleweed, am using it for 1 year now and want to continue using it but these errors freak me out.
Do I need to wait till a new update is available which will solve these problems, or can I do something to solve it now?
I wish I was better in understanding Linux but unfortunately I am not. I’m a computer user not a guru. I normally know what to do, how to make things work but now I am in over my head.

Hi
If you see the errors and everything is working ok, then talk to the hardware manufacturer to fix it (BIOS Update), else you could try raising a bug report and see if the kernel developers can shed further light. openSUSE:Submitting bug reports - openSUSE

I have talked to the service department of the manufacturer but when they heard I am using Linux instead of Windows the reaction was: we can’t help you, we only help if the pc’s hardware and software is in original state, which it is not. I erased windows completely to have more free disk space, so no way of going back.

Hi
Re-install windows? It’s a free download, or ask the manufacturer (or see in the support section) to send a recovery USB (generally free if under warranty) and duplicate? Else raise a bug report and see if that helps.

That’s probably the best you’re going to do…

ACPI “errors” are quite common: "ACPI BIOS Error (bug)" - Google Suche

for your particular one there is a good explanation in answer #2 here: kernel - ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GP17.VGA.LCD._BCM.AFN7] - Ask Ubuntu

You could report it as a bug against the kernel, but it’s likely to end up as “won’t fix”, here’s one I reported earlier: 1150570 – Assorted ACPI errors logged at boot.

Bottom line is you could try the latest upstream kernel from OBS Kernel:stable repository: Show Kernel:stable - openSUSE Build Service and/or a bios update. Personally, if the machine was working OK I’d just ignore the error…
