Sorry, I made a mistake. I kept editing my pf.conf while trying to figure this out and got confused as to what edits I had on exactly when the crashes happen. It seems to be related to the "counters" keyword of tables. I had it on at some point and it can cause crashes later on when you reload. table persist counters file "/etc/pf/firehol-level1-blocklist.tab" If I've been reading this stack trace and the disassembly correctly, the cr= ash must be happening right there: https://github.com/freebsd/freebsd/blob/releng/12.2/sys/netpfil/pf/pf_table= .c#L2112-L2113 2c228: 65 48 83 01 01 addq $1, %gs:(%rcx) --=20 You are receiving this mail because: You are the assignee for the bug.=
