For the code at https://svnweb.freebsd.org/base/user/pho/stress2/testcases/thr1/thr1.c, this only happens sequentially from the main thread, so that suggests something went wrong releasing the lock on the userland side (it shouldn't need to trap into the kernel). -- You are receiving this mail because: You are on the CC list for the bug.
