I partitioned my C: drive, downloaded a fedora 28 live boot to a thumb drive, and tried to boot it. When it starts, I get a stack dump as follows:
[Firmware Bug]: AMD-Vi IOAPIC[32] not in IVRS table
Kernel Panic - not syncing: timer doesn't work through Interrupt-remapped IO-APIC

For what it is worth, I got a very similar result with a Ubuntu 29 live boot.
Can anybody point me in the right direction?
