Hey guys, I'm currently dealing with an issue that's almost driving me insane.
Scenario: - FreeBSD FreeBSD 14.0-STABLE #5 stable/14-n266935-fdfb8e783c3e: Tue Mar 5 17:41:08 CET 2024 - Intel Core i7-8086K - Windows 11 Pro guest What I'm observing is that the VM guest generally boots and works fine without any issues. However, once I passthru a PCIe USB controller card, the VM seems to hang when Windows is booting. At that point, I can only kill -9 the bhyve process. Anything else just hangs (including bhyvectl --destroy). If I change the VM configuration to use only 1 CPU core, it boots fine 100% of the time with the passthru. The same is true if I give it 1 CPU core and 2 threads (boots fine 100% of the time). But once I give it more than 1 CPU core, it locks up when the passthru is enabled. Is this a known issue? I have seen [1] but I'm not sure whether it's the same scenario or whether there are any patches I could apply to get me out of this madness. I earlier posted here [2].
