This seems like a problem with your USB drive (or motherboard having too weak
USB controller to power the drive or something like that). Because the drive
disconnects after being mounted and later also gives IO errors. See:

And there are more IO errors because the drive then reconnects, gets sdf
assigned but disconnects again. Anyway, this is either USB stack or HW problem.
If you see it only with some kernel and not with other, it might be worth
pursuing further. Otherwise I'd try to play with HW...
