It would be nice if you build kernel with debugger and got a stack
backtrace to show where problem occurred.
Also, if you like your port multiplier to work much faster and stable -
I would strongly suggest you to update to 8-STABLE (or wait forthcoming
8.1-RELEASE, if you prefer releases) and use new siis(4) driver for your
SiI3132 SATA controller. Port Multiplier support in ata(4) driver left
in embryo level and won't be improved.
