problem with dwmmc ? panic's on bad filesystem...

[Søren Schmidt]

Hi

I have had this panic several times on rk3399 based systems when the filesystem has gone bad (and just needs a fsck). 
It doesn’t happen on Marvell a3720, so its not arm64 specific, more likely dwmmc specific or maybe the dma on the rk3399 ?

13-stable of today, but problem has been around for a long time..

Anybodu else seen this ? Ideas ?
