Gerd and i ported this driver from downstream and finally it's got merged in 4.12. So do you mean that you backported the mainline version to 4.4 or the downstream version of 4.4?

The card above is listed as OK and NOK. The experienced issues doesn't need to be direct related to the card (unproperly umounted, bad driver, ...).
