Hello, I'm curently reading the code of the function smp_rendezvous_action, in kern/subr_smp.c file. In that function, i see that the variable smp_rv_waiters is read in some while() loop in a non-atomic way.
https://svnweb.freebsd.org/base/head/sys/kern/subr_smp.c?view=annotate#l412 https://svnweb.freebsd.org/base/head/sys/kern/subr_smp.c?view=annotate#l458 https://svnweb.freebsd.org/base/head/sys/kern/subr_smp.c?view=annotate#l472 I suspect one of my freeze to be due by that. Should this function be patched to use "atomic_load_acq_int(&smp_rv_waiters[])" ? Best regards -- Alexandre Martins STORMSHIELD
