couldn't get size 0x800000000000000e after kernel upgrade

[panja]

I ran "apt update && apt upgrade".
My kernel got updated to GNU/Linux 5.0.0-23-generic x86_64 and now when booting I'm having an error message:
[ 1.494511] Couldn't get size 0x800000000000000e

Intel NUC7i5BNK (latest bios: BNKBL357.86A.0080) with Ubuntu Server 18.04.2 LTS with Secure Boot disabled.

Any one know how to fix this?

[panja]

Any one?

Have you tried with the enabled Secure Boot?

[panja]

Yes, I've tried it with Secure Boot enabled.
This gives me the same problem unfortunately.

Does your system still boot?

[panja]

It boots and I can use it without problems.
It's just not really nice to see error messages.

I'm using this machine in the living room as a retro game machine.
Normally it boots up without any prompts or screens but now I have this error message.

It's just not right...

I've seen the same 'couldn't get size' message several times on some computers in the past (but admittedly not for a long while, though). As long as there is no noticable effect on operation, you should consider it 'informational' and just live with it it. With some future update, it will probably go away.

You probably know this, but if you run journalctl -b you will see the journal messages generated on startup for the most recent boot. Lots of similar scary chatter in there, some even labeled with ERROR and WARNING. Sometimes some push through the splash barrier.

I just ran that on this computer looking for 'error' in the output:

---and there is more----

None of this appeared on the screen on startup. Scary, but don't be too alarmed.

journalctrl -b

Should be journalctl -b

[Dennis N]

Should be journalctl -b
Thanks; and corrected.

[panja]

Thanks guys!

I do know it’s more an informational message than anything else and normally I won’t be bothered much. But it’s a living room machine which is used by daughters and wife as well. They do get scared with messages like this. 😂

When you updated do you know if your grub.cfg was also changed?

I fix mine a different way. But I see this message when I install ubuntu but is controlled by another os.

[panja]

Sorry for the late reply...


Output efibootmgr:

This error exists for a long time in the Linux kernel of many distros. According to the link https://bugzilla.redhat.com/show_bug.cgi?id=974841 , it can be safely ignored if you don't use SecureBoot related stuff.
