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.
