2 USB ports randomly disconnect and don't reconnect (it's always the same two), and in dmesg all I get is

"
[ 1276.916458] ohci-pci 0000:00:12.0: HcDoneHead not written back; disabled
[ 1276.916467] ohci-pci 0000:00:12.0: HC died; cleaning up
[ 1276.916553] usb 3-1: USB disconnect, device number 2
[ 1277.017302] usb 3-2: USB disconnect, device number 3
"
This only started happening when Yakkety went to the 4.8 branch, with 4.7 branch this doesn't occur, hence the bug report since it's unlikely that a hardware failure will only stick to one OS and one branch of the kernel for that OS. (these USB ports don't randomly die on Windows or BSD, I've tested that in the past couple of days)

kernel version: 4.8.0.17.27
