Hello,
I don't know it that was cerb related or not, but I only have cerb as
third party module, so either is cerb or bug in freebsd (mine is
4.8)
rl0: promiscuous mode disabled
tap0: promiscuous mode disabled
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x26
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01ccf37
stack pointer = 0x10:0xcda45e30
frame pointer = 0x10:0xcda45e4c
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 89886 (python)
interrupt mask =
trap number = 12
panic: page fault
syncing disks... 56 45 35 16
done
Uptime: 91d3h55m20s
Automatic reboot in 15 seconds - press a key on the console to abort
I was playing with openvpn, and bridging, I belive result of crash was
when I unloaded bridging module.
My kernel was compiled with debugging symbols, but I don't know what
to do to get more informations.
I have also /var/crash/vmcore.0 file from crash.

Could you show backtrace? There is a description in developers-handbook how to get backtrace and how to load kld module symbols. --=20 Pawel Jakub Dawidek pa...@da...

Ehh, I was trying couple of the times, and it didn't give me any backtrace, I checked logs and I noticed this: Jan 7 16:15:21 freebsd /kernel: dumpon: Jan 7 16:15:21 freebsd /kernel: sysctl: kern.dumpdev Jan 7 16:15:21 freebsd /kernel: : Jan 7 16:15:21 freebsd /kernel: No space left on device Jan 7 16:15:21 freebsd /kernel: swapon: adding /dev/ad0s1b as swap device Jan 7 16:15:21 freebsd /kernel: Loading cerb... Ehh, sorry :((( Since last restart I installed more memory, but didn't increase swap, since I didn't wanted to destroy slices, damn. -- Best regards, Dariusz mailto:ce...@ta... http://eggdrop.takeda.tk - eggdrop help |

Some modules does not handle being unloaded very well, so I don't think it's unlikely that the problem is a FreeBSD bug and not Cerber. I just tested on my 4.9 crashbox and that didn't panic when I unloaded the bridge module, but of course the problem might have been solved after 4.8. --=20 Simon L.

You know what, I was unloading bridging and if_tap, on the logs I had: rl0: promiscuous mode disabled tap0: promiscuous mode disabled so I belive that bridging unloaded successfully, but system crashed while I was unloading tap device. -- Best regards, Dariusz mailto:ce...@ta... http://eggdrop.takeda.tk - eggdrop help |
