That driver clearly cannot be very well maintained. All the distro
kernels have the basic debug checks in place, afaik.

Is it some wonderful "enterprise hardware" garbage again that only
gets used in special data centers?

Becasue the "enterprise" people really are special. Very much in the
"short bus" special kind of way. The fact that they have fooled so
much of the industry into thinking that they are the competent and
serious people is a disgrace.
