I tried those options …

…and then I’ve changed “acpi=off” to “acpi=ht irqpoll” and no luck for the boot giving me this error:

I rebooted again with default grub argument (acpi=off) and I noticed only right now, and through CoreControl, that my CPU is affected by a considerable bug…

Which may drive into this case…

Keep in touch, got to sleep now.

Possibly faulty BIOS from MSI or from OS (kernel).
