(sorry about the delay, I've been away from this machine in the mean time)
I had to recompile the kernel to get a kernel.debug file, so the addresses in
the panic message have changed to:
Fatal double fault:
eip = 0xc0867e2b
esp = 0xd4225fd8
ebp = 0xd4226010
panic = double fault
So, using the new value of eip, I get this from objdump:
# objdump -d -l `find /usr/obj/ -type f -name kernel.debug` | grep -5 ^c0867e2b:
c0867e1f: 8b 5d 08 mov 0x8(%ebp),%ebx

c0867e39: 85 d2 test %edx,%edx
c0867e3b: 74 06 je c0867e43 <bus_dmamap_load+0x33>
Is that any use?
Thanks
Nicolai
