Hi Frank,
    Firstly, thanks for taking some time to look at this. Sorry, I cannot
try with a 1.5Gb/s drive as I don't have any.
    Below is the dmesg output for this machine with a current kernel as of
about 2 hours ago. The config is customised but not much...

include "arch/amd64/conf/GENERIC.MP"

no options      COMPAT_15
no options      COMPAT_16
no options      COMPAT_20
no options      COMPAT_43
no options      COMPAT_386BSD_MBRPART

no options      NS
no options      ISO,TPIP
no options      CCITT,LLC,HDLC
no options      NETATALK

Here's the dmesg...
