For me, bitten when I attempt to rebuild kmod ports after installworld. Instanlty hard-reboots without any core nor crash dump when actual rebuild starts. (I'm not using PORTS_MODULES variable, but building manually as part of upgrades after installworld and following etcupdate.) Bitten at: commit 8cc1c0f35ec8d5a3edb4ee1ede962a3c1f6baef0 Fixes by: Rolling back /usr/obj (separate dataset on ZFS) to commit 33345b8834859cf1ad7f1256f3a34b4a7c83e8e8 with commit 14b9955e57cc28b61e785165b9effcbe620edb46 reverted, Checking out commit 67b918e03475e780854a43fe4eb7c8e95f4deb29 buildworld, buildkernel, ... as usual Regards. -- Tomoaki AOKI
