I brought this up on this list a few months ago, and now with a minor lull in my courses, I did some debugging. I'd been getting "unknown phase" errors and was told that this was due to latency in the controller. It's not. It's due to a strong predicate in atapi.c. I changed #define PHASE_COMPLETED (ARI_IN | ARI_CMD) to #define PHASE_COMPLETED (ARI_CMD) and the unknown phase (the more common problem for me) goes away. Apparently, the controller doesn't assert ARI_IN when the ATAPI_MODE_SENSE command is done. Question: Is this change to PHASE_COMPLETED, albeit a weaker predicate, safe? And can someone commit this change to -current? -scooter -- Scott Michel | In life, there are sheep and there are UCLA Computer Science | wolves. PhD Graduate Student | ... And I don't bleed ...
