Hi, Using kernel 4.4 or more (4.8.11-1 on arch), an USB 3.0 external HDD dies all the time when writing on it. Tested on multiple computers, multiples disks, and multiple external disks. Only works on my 3.10 kernel (CentOS7). On dmesg I got this : [ 117.372521] sd 2:0:0:0: [sdb] Synchronize Cache(10) failed: Result: hostbyte=0x07 driverbyte=0x00 [ 117.776461] usb 2-2: new SuperSpeed USB device number 4 using xhci_hcd [
