Ok, I found the reason: I was passing a single page for the
page_table, which I guess corrupted the whole stack !!
Eventually, I fixed the same. but ran into another issue ? Should
trigger not sleep or something that way ?
Currently, I see the issue as follows in the log, but if the
ops->run() callback is commented out I don't get that
weird message/error about lock states.
Now, ops->run(), ie xs2dtl_run() is called with other other streams,
such as an MPEG stream, where it doesn't
show any issues.
Any idea, why uncommenting ops->run() produces that message ? Should
trigger not sleep ? Confused ...
