[Bug 268744] Running the wifibox (bhyve VM) crashes system with vmm lock error

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268744 --- Comment #1 from bj...@baerlin.eu --- This seems to be an issue with pci-passthru, a vm with pci-passthru crashes the host, same vm without pci-passthru works -- You are receiving this mail because: You are the assignee for the bug.

Re: Windows 11 22H2 with passed-through PCI devices hangs in vm_handle_rendezvous() at boot

So it looks like the problem is: - in one thread we call vcpu_set_state_locked() [from a VM_MAP_PPTDEV_MMIO call from userspace] -- both the new and old states are VCPU_FROZEN -- the threads enters a loop while vcpu->state != VCPU_IDLE -- it gets stuck here forever since nothing will ever change
