Hi: Sorry again, The last email was wrong, fixed my email to not send html email and respond again. The drivers manufacturers advertised high speed support platform is Windows,MacOSX, not include linux 4.9 , this bug will affect the users normal use, run iozone is just one of the behaviors that trigger UAS crash ,We will handle that slow issue.

I do not understand why there are failures on Linux, yet not on other operating systems. If you run iozone on OS-X, does the same errors happen? How about a storage stress-test on Windows? Why is Linux going to have to make these devices go very very slow and what will happen to the users that now can not operate their devices at the advertised speeds? Who will handle that support issue? thanks, greg k-h
