Ok, easy enough. Should *any* PCIe passthrough work on Epyc right now? Just trying the same thing with a simple PCIe USB card gives me: CPU0: local APIC error 0x40 CPU0: local APIC error 0x40 ivhd0: Error: completion failed tail:0xda0, head:0x0. ivhd0: Dump all the commands: [CMD0, off:0xff0] opcode= 0x0 0x0 0x0 0x0 [CMD1, off:0x0] opcode= 0x3 0x0 0x0 0x7ffffffffffff003 [CMD2, off:0x10] opcode= 0x0 0x0 0x0 0x0 [CMD3, off:0x20] opcode= 0x2 0x0 0x0 0x0 [CMD4, off:0x30] opcode= 0x2 0x2 0x0 0x0 [...snip... lots of similar stuff] Then I get a bunch more APIC errors, and the system freezes for about 60 seconds before recovering. -- Kevinhelp
