Hello,
I am trying to run Mystique SaTiX-S2 CI Dual cards to fetch and decrypt a number of channels 24/7. I got it to work with the ngene/cxd2099 drivers (passing the stream through the sec0 device etc), but one remaining issue is that the driver occasionally reports a command timeout followed by more errors from the CI:

>From the moment that happens, I can't do anything with the card: all ioctls fail even after re-opening the adapter or after reloading the drivers. Only a reboot can bring it back to a good state.
This condition is not so frequent, I've seen it happen maybe 5 times running a dozen cards for a week. Has anyone experienced it? Is this something the driver would be able to recover from?
Versions details below,
Thanks,
