Quite. The thing that's puzzling me, though, is this: There are a lot of
phy events occurring during normal operation that get cleared by the
interrupt handler. However, during link autopsy, phyrdy and comwake are
set in SError even though event notification has not been disabled yet
at this point. This suggests to me that not all changes to those bits in
SError are brought to our attention through event notification, at least
as long as ALPM is enabled. Besides, I'm wondering whether that many phy
events are to be expected (i.e. observed on other controllers too) when
ALPM is enabled.

Elias
