BTW, the patch as present verbatim in the posted link
( seems to be incorrect.
Either the register should be 0x53 and should be accessed via byte access.
Or the bit should be 27.

And, BTW, that bit of that register is not documented in AMD SB700/710/750
Register Reference Guide -- bits 24:27 of EHCI Misc Control register are said to
be reserved.

It's interesting to understand what this bit actually does, maybe someone has
contacts at AMD.
