I doubt that.  Have you confirmed it with testing?  When you install
module cpu-tegra, the pcie initialization has been done, right?

Before we head to a solution, we need to identify the cause.

One thing I note is there is no loops_per_jiffy updating in cpu-tegra
driver.  But if I understand correctly, the driver is running on
MP system.  It should update loops_per_jiffy when cpu frequency
changes, right?  I'm worrying about that the timeout in tegra pcie
driver just happens to work with a wrong loops_per_jiffy, but becomes
broken when loops_per_jiffy gets correct.
