 Hi,
 
 It can be SPARC or SSD specific issue, I am using it relatively
 successfully on the x86/amd64 system.
 
 However, this controller is quite fickle from my experience. I've seen
 quite similar errors because of "bad" SATA cables or maybe power
 connectors.
 
 Of course, if Linux consistently works correctly with the same device,
 likely the problem is elsewhere.
