This change causes fsck_ffs(8) and mount(8) to hang unkillably on sparc64 when the kernel is built with either GEOM_PART_GPT or GEOM_LABEL. When breaking into the kernel the backtrace so far looked like one of these two ways: g_wither_washer() at g_wither_washer+0x18 g_run_events() at g_run_events+0x4dc g_event_procbody() at g_event_procbody+0x8c fork_exit() at fork_exit+0x9c fork_trampoline() at fork_trampoline+0x8 find_instance() at find_instance+0x80 _sx_xlock() at _sx_xlock+0xf0 g_run_events() at g_run_events+0xb0 g_event_procbody() at g_event_procbody+0x8c fork_exit() at fork_exit+0x9c fork_trampoline() at fork_trampoline+0x8 I've no clue about geom(4) so I also have no idea how to debug this.
