Hi,
I modified the GENERIC kernel with the following options
options BRIDGE
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=10
options DUMMYNET
I added the following lines to /etc/sysctl.conf
net.link.ether.bridge=1
net.link.ether.bridge_ipfw=1
The kernel compiled fine and I was able to boot
Then I added the following to /etc/sysctl.conf
net.link.ether.bridge_cfg=fxp0,em0
and a line to /boot/loader.conf
bridge_conf="YES"
Now I cannot boot into the system!!
I am getting the following message during boot:
net.link.ether.bridge_cfg
Fatal Trap 12: Page fault while in kernel mode
fault virtual address 0x10
fault code supervisor read, page not present
instruction pointer: 0x80:0xc0229f5b

trap number 12
panic: page fault

Automatic reboot in 15 seconds
The problem appears to be the statement that I added to sysctl.conf. Can
someone help?
How do I boot back into the system?
Thanks
Girish
