I've now hit again a firmware crash with ath10k with the latest firwmare and kernel and the *only* thing that helped recovery was a full reboot, so that is a crystal clear case that this needs to taint the kernel, and yes we do want to inform users too, so I've just added uevent support for a few panic / taint events in the kernel now and rolled into my series. I'll run some final tests and then post this as a follow up. devlink didn't cut it, its networking specific. Luis
