If you confirm that module-card-restore indeed has to be disabled even
with the increased timeout, then it would be very interesting to know
what effect module-card-restore has in the card initialization. To me
it seems that it should make no difference, because the a2dp profile is
the default anyway, and all the module does is to choose the initial
profile.
