RT-AC86U Watchdog & mtd9 scan

[CaptnDanLKW]

I noticed this in my logs yesterday. Never seen it before. RT-AC86U with 384.18_beta1

It seems that something went wrong and the watchdog daemon caught it, but I'm bewildered by the actions taken. Perhaps a listing of the function <> partition mapping can shed some light?

Is mtd9 really the nvram partition, that was seemingly mounted as a file system, checked, and then dismounted and released back to the OS?

Hardware fluke, software bug? Thoughts?

Searching the forum those UBI messages appear to be pretty normal. So unless you're seeing a lot of them I'd ignore it.
