Intel NUC NUC6CAYH - cannot install CentOS 7.5

Post by pxsh » 2018/05/18 23:23:33

Hi,
I´m unable to install CentOS 7.5 on my new NUC6CAYH NUC.

ISO: CentOS-7-x86_64-Minimal-1804.iso
Model: Intel NUC - NUC6CAYH (j3455 celeron @ 1.5GHz).

After selecting "Install CentOS 7" I get this text, which is present for about 2-3 minutes:

[ 0.0000000] Detected CPU family 6 model 92 stepping 9
[ 0.0000000] Warning: Intel Processor - this hardware has not undergone upstream testing. Please consult...."

Then after 2-3 minutes the installer flashes to a black screen, pressing any key during the black screen brings back a wall of text:

Then a black screen and pressing enter again loads more text:
http://www.pxsh.se/pub/img/centos7/20180517_171307.jpg

After ~10 minutes this comes up and thats the end:

I´ve used most of my google skills and what I´ve read one should be able to press escape to enter a console and write "linux text" to begin installation in text mode but I never come to any console mode when pressing ESC.
Pressing c gets me to GRUB console and e is for editing params for the install but it results in the same procedure even if I add "inst.text" bootoption as specified by anaconda startup.

Happy for any help here.

If you press Ctrl-Alt-F2 you should be on a root command prompt to have a look around. Check the output from `free -m` to make sure it is seeing all your RAM for example. On F3 and upwards you should also find screens showing the content of various logs and those may well be informative. I'd also look in /var/log/Xorg.0.log (could be in other locations like /tmp or /mnt/sysimage/tmp).

If you are installing using a USB stick, did you read http://wiki.centos.org/HowTos/InstallFromUSBkey and avoid all the utilities that are listed there that are known to BREAK the iso as they copy it. Did you check the sha256sum of the downloaded iso file against the list in the CentOS 7 Release Notes https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 to make sure it is correct?

You probably don't want to use the text mode installer anyway. It's extremely limited and doesn't allow for customization of anything. No partitioning. No filesystem choices. Avoid if at all possible.

sha256 sums compared and verified.
Tested 3 different USB memory sticks (different brands also), and tested thru all 3 available USB slots on the NUC, no success, same issue.
I get the same behaviour for "Install Centos 7" and "Verify this media and install Centos 7" from the menu.

Ctrl+ALT+F2 does not bring me to any console, neither in the install menu nor when its loading.

Tested with these tools (In Windows 7):
Win32 Disk Imager (the recommended tool)
Rufus
Unetbootin

Both unetbootin and rufus are on the "do not use" list, Rufus because some of its options result in iso corruption. Never used your 3rd choice. The absolute safest tool to use is plain old 'dd' as it doesn't try to be clever, it just copies what it's given.

The bad news is that your cpu is in the group formerly known as Apollo Lake.

https://www.intel.com/content/www/us/en ... j3455.html

Good support for Apollo Lake appeared in kernel 4.13, hence all the warnings at boot, and the EL7.5 kernel does not seem to support it very well, if at all.

The best option for you, once EL7 is installed, is to install/boot elrepo kernel-ml (kernel 4.16) until the stock kernel catches up or EL8 comes out.

I have 2 Apollo Lake-based systems that ran very slowly under the stock EL 7.4 kernel, but they did install / run. After installing the elrepo kernel-ml, they both ran great! Actually, better than great. :D

I could not get the systems to boot EL 7.5 kernels last time I checked.

If failures continue, my suggestion is to install EL 7.4, upgrade to kernel-ml and then update to EL 7.5.
