The drive is bus 1, device 3. The last bulk input submission apparently never receives a response (I watched it for a while, and after several minutes it was still stuck on the last line.) Is this a sign of a broken device? Even if it is, is the kernel mishandling this by hanging forever? (I'd be inclined to say yes, but maybe there's only so much the kernel can do with broken devices...) -- You are receiving this mail because: You are the assignee for the bug.
