I checked the bios settings and uefi was the only boot option, so there is no legacy mode what I had used with my old computer before. I downloaded the normal iso image and made an usb boot pendrive using mkusb. The boot was okay, I got an uefi type menu but after starting the kernel it paniced(?) instantly. - Error messages: ACPI Error [MAC0] Namespace lookup failure - ACPI ERROR 1 table load failures, 13 successful - BUG: soft lockup CPU#0 stuck for 22s - ... - ... - EFI VGA framebuffer device - clocksource tsc mask - Switching to colour framebuffer device - [28.040001] ... - ... - ... - I've tried to boot the same pendrive on my girlfriend's Acer Travelmate - with uefi and worked well. + This is a brand new notebook on the market with Ryzen 5/Radeon. + The default kernel of Ubuntu(18.04) hangs at loading with message: - I searched and I found that the problem is maybe in connection with uefi - framebuffer but I am not sure. + tsc: Refined TSC clocksource calibration: 1996.250 MHz + clocksource: tsc: mask: 0xffffffffffffffff max_cycles: (...), max_idle_ns: (...) + Soft lockup - Ubuntu 16.04 can be loaded with nomodeset and noacpi parameters but for - 18.04 none of them are working.
