big.LITTLE status for rk3399/rockpro64?

[Vincent Milum Jr]

I can confirm that USB Mass Storage causes kernel panics ~50% of the time.
This happens during detection/initialization of the device.
Leaving the drive in during boot has the same chance of panic.
It is not 100%, as sometimes I can get the drive to register and use it.
I've yet to see any other USB device have an issue though.
I'm actively using a USB-3 hub with keyboard, mouse, and ethernet without
issue.
