With disabling the loading of 'mac_portacl' in the loader promt the system starts up without problems. The problem can then be triggered manually by loading the module 'mac_portacl' and restarting a network related service of choice. (devd, cron does not trigger) Wen triggering the panic by restarting sshd I get the following: ------ panic. rm_lock: recursed on non-recursive rmlock mac_policy_rm @ /usr/src/sys/security/mac/mac_framework.c:198 cpuid = 3 KBD: enter: panic [ thread pid 2178 tid 100814 ] Stopped ad kbd_enter+0x3e: movq $0,kdb_why db> ------- I created a dump and put the bt on http://pastebin.com/pfBZtcdy In my /etc/sysctl.conf I have the following lines regarding mac_portacl: .. security.mac.portacl.port_high=1023 net.inet.ip.portrange.reservedlow=0 net.inet.ip.portrange.reservedhigh=0 security.mac.portacl.suser_exempt=1 security.mac.portacl.rules=uid:53:udp:53,uid:53:tcp:53 .. >From the commit log, for me r252209 looks like it could have something to do with this. I don't know if other MAC-modules are affected, too. >How-To-Repeat: boot with module 'mac_portacl' enabled or kldload mac_portacl && /etc/rc.d/syslogd restart (restarting any network related service is ok) >Fix: >Release-Note: >Audit-Trail: >Unformatted:
