You have told much and same time gave nothing that can be used.

What controller do you have? What drives on what channels? Is there any 
kernel messages about the problem? Have you tried to enable verbose 
messages to get additional details?

Reinit could return ENXIO if it already was in progress. Disappearing

hardware problem?
