I installed Ubuntu 18.04 on Asus X550V, downloaded from the official website. The installation processes went all without any errors. After starting Ubuntu, I updated it, then restarted the PC. When it started, it hangs on the boot screen with this error: Unable to run on non-Dell system
I rebooted it again and opened Advanced options for Ubuntu on grub then I chose to boot on an old kernel 4.15.0-20-generic (The latest kernel in my PC is 4.15.0-23-generic). The PC started without any errors.
But when I run dmesg, I encountered the following errors:

[    1.162410] Couldn't get size: 0x800000000000000e

[   12.771862] dell_smbios: Unable to run on non-Dell system

That seems very strange to get an error about Dell in an Asus PC.
Is there any explanation and solution for this?

PS: The PC has an Nvidia GTX 950M graphic card.

    You need to install Nvidia drivers. That message is not related to the problem.

I am running Ubuntu 18.04 on Dell Precision T5500, and also receive dell_smbios: Unable to run on non-Dell system from the kernel. The system seems to run perfectly normal. I believe that the message is coming from libsmbios. libsmbios-c2 was installed automatically. It is provided by Dell, and is looking for vendor specific BIOS extensions.

It appears that this is not a critical error, and may be treated like a warning message.
