This is a hard one to solve thanks to Justin and his idiot my driver
knows best policies.
The problem is essentially that recovery can take time and the mid-layer
will get impatient and use a bigger hammer. Justin, therefore, tries to
hold of the timeout until recovery has finished (which can apparently
take forever in his driver). Just pulling out the timer adjustment
might be a welcome cosmetic fix, but it won't solve the underlying
problem: we'll have the mid-layer thinking the command is aborted and
the aic driver still trying to process it.
