Try this patch, instead?
Yes, I was testing a similar patch to yours (skip calling wdstart() when !device_is_active()) after my previous email. It did not crash so far. I'm now running with your patch and will be back in a week or so. It will take some time because the panic tends to occur after an overnight sleep rather than a short nap. -- KAMADA Ken'ichi <kam...@nanohz.org>
