Some messages on boot

balancana · 2018-02-08 09:48:33

I installed Arch linux on Lenovo Z50-70. Also I have dual boot with Win10 and Ubuntu 16.04.03.

Laptop specs are:

CPU: Intel i5-4210U (4) @ 2.700GHz
GPU: Intel Haswell Mobile
GPU: NVIDIA GeForce 840M
MEM: 7876MiB
KERNEL: 4.15.1-2-ARCH

Here are messages I got on boot:

After a little google I found same problem on following link: https://unix.stackexchange.com/question … pkginit-38
There is suggestion to update bios, so i switch to Win10 found bios update exe file on official Lenovo website and installed it.

After update some of messages disapeard, but still there are some:

The thing I noticed, if I change Graphic Card in bios to Descrete instead of UMA only, there is only one message:

intel-spi: unrecognized JEDEC id bytes: 1c, 70, 17

But I want Geforce 840M to be enabled, so I can install NVIDIA prime to play games

Please replace the oversized images with thumbnails or links, see the forum rules.
Is there an actual problem (does the system boot) or do you just mind the ACPI errors? Latter have been discussed on this forum ad nauseam.

I am just curious about ACPI errors, what they mean? And why they appear only when I enable both graphic card (Nvidia and intel) via BIOS (Graphic Card = Discrete).
I didn't succeed in setting up NVIDIA prime yet, is that somehow connected with ACPI errors?
