Bernhard, >> And I am guessing your device does not trigger a Unit Attention as a >> result. You don't see something like "Inquiry data has changed" or >> "Capacity data has changed" in the log, do you? I have been working on a set of patches that will address devices like this that change their tune halfway through discovery. Your case is really just the tip of the iceberg, more changes are needed to handle this gracefully. I'll try to get these changes completed in time for 5.7. However, we need a smaller fix for 5.6 and stable. Can you please try the patch I just sent? Thanks! -- Martin K. Petersen Oracle Linux Engineering
