Kernel Panic on Rock64 linux
#16
I saw a kernel panic w/ xenial-minimal-rock64-0.4.17-85-arm64.img after I unplugged a USB 3.0 hard disk (nothing was mounted on it).  Seems like the OS thought it was still connected.

[ 7800.498794] INFO: task parted:5470 blocked for more than 120 seconds.
[ 7800.499779]       Not tainted 4.4.70-rockchip-ayufan-85 #1

Playing with jessie-minimal-rock64-0.5.7-101-arm64.img now, and don't see the same issue.  It does take several seconds for it to decide the USB device is no longer available when I unplugged the cable.  Nothing was active when the cable was unplugged, it just spewed the following to the console :
[  873.393783] usb usb5-port1: Cannot enable. Maybe the USB cable is bad?
[  873.394805] xhci-hcd xhci-hcd.8.auto: Cannot set link state.

Edit: Looks like the latest jessie minimal also panics after disconnecting USB 3.0 device. Filed a issue on github, with ayufan (not sure if it was the right project page though).
