But that is beside the point, because: It is not valid to have a preferred I/O size smaller than the minimum I/O size - this should be obvious to the vendor. We can detect this at mkfs time and error out or ignore the bad values, but there can be no debate about whether the hardware is returning nonsense. It /is/ returning nonsense. That's a firmware bug. Pose the question to broadcom: "How can the preferred IO size be less than the minimum allowable IO size? Because that's what the hardware it telling us. -Eric -- You are receiving this mail because: You are watching the assignee of the bug.
