On MT7915, MCU hangs do not trigger watchdog interrupts, so they can only be detected through MCU message timeouts. Ensure that the hardware gets restarted when that happens in order to prevent a permanent stuck state.
We applied this to our hacked upon 6.10 kernel, and this patch appears to cause NPE down in debugfs file removal during radio restart. We didn't investigate this closely, but removing this patch fixes the problem. Also of note, we see the radio have a timeout, but then recover, often (without this patch). Did you force/fake this situation to happen and see it actually work? Thanks, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com
