Hi,

I am wondering if anyone encountered this issue on IMX8. It is very intermittent.

Sep 11 07:26:20 colibri-imx8x kernel: fsl_lpspi 5a030000.lpspi: I/O Error in DMA RX
Sep 11 07:26:20 colibri-imx8x kernel: spidev spi2.0: SPI transfer failed: -110
Sep 11 07:26:20 colibri-imx8x kernel: spi_master spi2: failed to transfer one message from queue

Any input is highly appreciated.

Thanks,
Dionie
