System panic when boot at ISL using hpux -f3 /stand/vmunix

I am trying to use RS-232 communicatons for kernel/driver NDDB debugging. When booting target 9000/785 PA_RISC2_0 Bxxxx at ISL using hpux -f3 /stand/vmunix, the system panic at io_map_regs().. But if I boot at ISL using hpux /stand/vmunix then on panic! Why?

Thanks

even though I can't quite fathom what -f3 does, from the man-page it seems to me that it rewrites kernel io-maps, thus panic.
maybe that helps a little.
do what you can. don't if you can't.

Thanks, Dan,

How and where did you get the man page for io_map_regs? I couldn't find it on line or from HP-UX man pages.

i suggest as a hint:

man hpux
man pdc
man isl
man -k kernel
man ioinit

and take it from there
