As I said, OS installation went fine (brand new machine), but then I installed mate as it was described in the docs and then I received the following message after reboot :
[0.000000] Cannot reserve 256MB crashkernel low memory, please try smaller size.

Unable to type after this message. Any help is appreciated (explain it as you would to your grandma, I’m a total noob). There’s a lot of RAM in that rig, a quick search made me think that could be the cause of the first line, that is as far as I got…
