Using v9_pre1, I get a kernel panic in edma_dma_pause() on echan->edesc being NULL. I do get data before this happens. This is at high speed, high rate. No mention of the irq having too much to do, though. The more data I transmit, the more likely this is to occur.
I don't currently have the setup to lower the baudrate. I would probably need to reproduce this on a beaglebone, instead of our custom board. I'll see if I can do that.
If you need more info, just let me know.
Thanks, Frans
