I booted the one sy= stem experiencing this issue, a NUC8i5BEK, and when running 'jail -r , the interface stops responding for several seconds while the jail shuts down and the em0 interface is removed from bridge0. I can test this by pressing a k= ey several times in an SSH session and there will be no input/output until the interface picks back up. Conversely, if I use net/intel-em-kmod, after patching it slightly to make it work with 15.0-RELEASE, the hang does not happen and you can type stuff while the 'jail -r' command is running. --=20 You are receiving this mail because: You are the assignee for the bug.=
