Terje,
In my SAS Stack, I _do not_ have that switch statement in that
function. Apparently you are using "libsas", which is based
on an early, early version of my code, which bottomley and his
gang of SAS experts appropriated to "maintain". And as your
problem shows has been "fixed" in many ways.
You should complain to them -- I've CC-ed the linux-scsi mailing
list.
BTW, I don't experience this bug with the SAS Stack as I maintain it.
