I've only exercized read for now. In short, I've disabled all negative tests. I also activated Sense on error, although this seems to have no effect (more tests would be needed to prove = this for sure). If I leave "Random" for the I/O size, tests appears to stall from the start, fails after 10s of seconds and the device is disconnected then reconnected. If I choose "Increasing", "1 block" or "1024 blocks", tests complete successfully. In addition, there is a troubling fact. KT_32G is not recognized on the cas= e's front plugs, as reported earlier, but now also one of the MB's hub doesn't recognize it anymore (it did before, I tested the stick plugged there, see SD_64G_usbtest_3.txt). The machine has not been rebooted at all since I sta= rted testing and collecting data. --=20 You are receiving this mail because: You are the assignee for the bug.=
