Hi everyone,
I have been trying to boot OpenBSD on a Hillstone SG6000-E1700 firewall
appliance. It is a custom build appliance by Hillstone networks, but seems to
use mostly of the shelf components. I have been able to get it to load the
kernel via TFTP but it stops with the error “Trap cause = 7 Frame
0x9800000020007a58”. I’ve tried to debug this to the best of my ability and
read through some of the source code, which to me suggests that it’s throwing a
/* Bus error on a load or store */. But this is stretching far beyond my
abilities to understand currently.
If there is anymore information needed to debug this problem then I will gladly
provide it.
Below you will find the boot log and some of the DDB output as outlined in the
guidelines.
