This option is stated EXPERIMENTAL as you know and will never get
supported differently since it requires SYMBIOS compatible implementaion
of the LED support through GPIO0 and DIFFENTIAL SCSI detection on GPIO3
reading ZERO.
I cannot get sure it is safe since it probes the vendor specific part of
the chip called GPIO (General Purpose Input/Output) wiring that is board
implementation specific.
It may have been a misprobed DIFF that broke everything. The driver
prints out this feature if it will use it, but perhaps, the message text
scrolled to fast on your console.
I probably should WARN more loudly about this option in the kernel
configuration help.

Btw, I have been confused by the bogus value (194) reported by the driver,
and, frankly, I donnot have, for now, a single bit of explanation about.
