Hi We get kernel panics when we reboot either one of our two OpenBSD 4.6 servers running pf. It seems that the kernel panic always happens at the point where the pf sync state import happens. Sometimes we can reboot the servers, one at the time, a number of times in a row without any problems. We have tried to understand why this occurs but to no avail, is there anyone who could advise us what to do to try and resolve this?
The error message say: "fatal page fault (6) in supervisor mode trap type 6 code 0 eip d031baf5 cs 50 eflags 10297 cr2 2c4 cpl 40 panic: trap type 6, code=0, pc=d031baf5 . . . --- trap (number 6) --- pfsync_state_import(d899e83a,2,2d0,de1b4bc8) at pfsync_state_import+0x75" We have two identical servers running OpenBSD 4.6 and pf, they are build on the Supermicro X7SBT motherboard: http://www.supermicro.com/products/motherboard/Xeon3000/X48/X7SBT.cfm They have a totalt of six nic; two internal Intel PRO/1000MT (82573E) and (82573L) and four Intel PRO/1000 QP (82571EB). The pfsync interface uses em4 (that is the first of the two internal network cards - Intel PRO/1000MT (82573E)); pfsync0: flags=41<UP,RUNNING> mtu 1500 priority: 0 pfsync: syncdev: em4 maxupd: 128 defer: off groups: carp pfsync And we have a simple rule pass quick on { em4 } proto pfsync "ps -N /var/crash/bsd.0 -M /var/crash/bsd.0.core -O paddr" gives; PID PADDR TT STAT TIME COMMAND 12176
