Hi,

I do have a Highpoint RocketRaid 2220 controller myself which throws  
similar errors since the release of 8.0-BETA2. Tracking the commits, I  
could narrow it down to r195534.

The issue is, that htprr makes use of xpt_scan_bus() which ist no  
longer available in xpt_action[_default]() when cpi->transport is not  
set to one of XPORT_*. This probably affects all drivers relying upon  
xpt_scan_bus() but not setting cpi->transport.


This patch has been tested against latest head and stable/8 with no  
more issues for me.
