Comment(by marcusoverhagen):
Your proposed patch is no valid solution.
The initial port reset is required to
ensure that device signature is readable.
Your patch removes this reset. But the same
problem can also be triggered by hotswap of
sata device.
We seem to have a problem handling the
PhyReady Change / Port Connect Change
interrupts.
Unfortunately r31014 completely changed
the reset handling. The device is also no
longer reset before executing a command
when a reset request is pending as result
of an error interrupt.
Does reverting r31014 help?
