https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215972 --- Comment #21 from Peter Grehan <grehan@FreeBSD.org> --- (In reply to dgilbert from comment #20) Sorry, didn't know that was you. There are 2 other things to try here: - when the guest is hung, on the host issue bhyvectl --get-rip --cpu=3D0 --vm=3D<your vm name> bhyvectl --get-rip --cpu=3D1 --vm=3D<your vm name> bhyvectl --get-rip --cpu=3D2 --vm=3D<your vm name> bhyvectl --get-rip --cpu=3D3 --vm=3D<your vm name> You can look at what the resulting RIP values correspond to by restarting = the guest, and within the guest, kgdb /boot/kernel/kernel x/i <rip value> - Run the same test with a 12-current guest. With luck, it will panic and d= rop into ddb. If it hangs but doesn't panic, for the guest to drop into ddb from the host by issuing bhyvectl --inject-nmi --vm=3D<your vm name> From within ddb you can issue a backtrace. --=20 You are receiving this mail because: You are the assignee for the bug.=
