Hi, I think that this is similar problem as what David Hill send on tech@ with subject "splassert on boot"
I've checkout tree few minutes ago and in there should be mvs@ "Remove netlock assertion within PF_LOCK()" and dlg@ "get rid of NET_LOCK in the pf purge work" diffs. on boot I'm getting this splassert splassert: pfsync_delete_state: want 2 have 256 Starting stack trace... pfsync_delete_state(fffffd83a66644d8) at pfsync_delete_state+0x58 pf_remove_state(fffffd83a66644d8) at pf_remove_state+0x14b pf_purge_expired_states(1fdb,40) at pf_purge_expired_states+0x202 pf_purge_states(0) at pf_purge_states+0x1c taskq_thread(ffffffff822f69c8) at taskq_thread+0x11a end trace frame: 0x0, count: 252 End of stack trace. splassert: pfsync_delete_state: want 2 have 0 Starting stack trace... pfsync_delete_state(fffffd83a6676628) at pfsync_delete_state+0x58 pf_remove_state(fffffd83a6676628) at pf_remove_state+0x14b pf_purge_expired_states(1f9c,40) at pf_purge_expired_states+0x202 pf_purge_states(0) at pf_purge_states+0x1c taskq_thread(ffffffff822f69c8) at taskq_thread+0x11a end trace frame: 0x0, count: 252 End of stack trace. and if i destroy pfsync interface and then sh /etc/netstart box panic uvm_fault(0xffffffff823d3250, 0x810, 0, 1) -> e kernel: page fault trap, code=0 Stopped at pfsync_q_ins+0x1a: movq 0x810(%r13),%rsi TID PID UID PRFLAGS PFLAGS CPU COMMAND * 68977 95532 0 0x14000 0x200 3K systqmp pfsync_q_ins(fffffd83a6676628,2) at pfsync_q_ins+0x1a pf_remove_state(fffffd83a6676628) at pf_remove_state+0x14b pf_purge_expired_states(1f9c,40) at pf_purge_expired_states+0x202 pf_purge_states(0) at pf_purge_states+0x1c taskq_thread(ffffffff822f69c8) at taskq_thread+0x11a end trace frame: 0x0, count: 10 https://www.openbsd.org/ddb.html describes the minimum info required in bug reports.
