 |

I'm experiencing some log spam regarding my BDROM. There is no disc in the drive yet it complains about an unaligned transfer. Is this some sort of host-bus error?

OP: Generally, if post length permits, you should edit extra information into your first post instead of replying to it. Some users run a canned search for threads with zero replies as a way of finding posts to answer. When you replied to yourself, you removed your thread from that list, even though you were not replying to announce that the thread was solved. Thus, they would no longer see your thread on the list of unanswered threads.

| I would bet the drive is defective before the controller, but yeah, one or the other. Much less likely is a kernel issue. |

| The drive functions correctly, despite the log spam, under Windows and Linux. It just doesn't seem to like the responses to the INQ. |
