Do you mean "all normal processing" for that channel stops,
or *ALL* processing on all libata channels stops?
Obviously the former, I presume.

Yeah, the former of course. ;-) Error state is indicated by one of
the followings.
* ATA_FLAG_ERROR : one or more errors have occurred and EH is
scheduled to run.
* ATA_FLAG_RECOVERY : EH in progress
When either of above flags is set, only commands w/ ATA_QCFLAG_PREEMPT
flag set gets to run and complete. So, currently, sense requesting and
NCQ log page reading are done w/ the flag set.
