Hello I have a new Thinkpad T440p running debian with custom kernel 3.14.19. When I connect an external 2TB USB3 hdd, after 50-60Gb data written XHCI drops the usb device (just like I would pull the plug on it) then it comes back: I'm 100% that this is not a hardware issue because the drive works flawlessly from Windows7/8 on the same laptop. I did extended speedtests, surface tests with HD Sentinel and copied a lot of data on it on ~110 MB/s speed. It also only occurs with the high speed USB3 driver. If I use an USB2 only port where it negotiates a speed around ~ 25MB/s that's fine. I attach the log, lspci, lsusb outputs. Should I ran even more recent kernel than the 3.14? Were there any major improvements made in the XHCI driver? If so which kernel version is recommended? I want to use BTRFS as well, so need a version which performs well with that. Thank you!
