Hi Dirk, thanks for this report! > Is there any chance that there is a race condition where the timer function > sci_dma_rx_timer_fn() is called while s->chan_rx is invalidated, already. > E.g. via sci_dma_rx_chan_invalidate()/sci_dma_rx_release()? Or anything > else? Sounds a bit like the TMIO race condition you recently reported and which we luckily fixed meanwhile. I could have a look next week. Or do you want to handle it, Geert and / or Biju? Happy hacking everyone, Wolfram
