Is this still a problem, or have you found a solution in the meantime?

It also affects how the PCI core handles the device.  But as you said,
if you had the message before, it's probably not the cause of the
current problem.

>> 2) regarding the comparing of printouts:

Can you post the complete logs somewhere, maybe in a bugzilla or similar?

Where are the "PCIE ERR_CAP_STAT" and similar messages from?  My quick
grep didn't find them.
