Your commit comment is
"Collapse aac_map_command() into aac_startio(). Check the AAC_QUEUE_FRZN in
every iteration of aac_startio(). This ensures that a command that is
deferred for lack of resources doesn't immediately get retried in the
aac_startio() loop. This avoids an almost certain livelock."
This livelock, would i not still be able to drop into
ddb via the console?
i'm trying it out now, will post back with results.
The lockup varies between every couple of hours and ~3 days,
so it will take a bit.
