--- Comment #10 from Mark Johnston <ma...@freebsd.org> --- There is an instance of FUTEX_CMP_REQUEUE (op 132). This operation moves sleeping threads from one umtx queue to another, possibly changing the queue keys in the process. This is implemented by umtx_requeue(), not used by the native umtx interface in FreeBSD. So this can certainly lead to the bug, since umtxq_sleep() does not expect the queue hash to change. -- You are receiving this mail because: You are the assignee for the bug.
