I confirm this fixed the division by zero, thanks for the super-fast reply. FWIW, I am now getting a "normal" error message now: [ +1.046688] spidev spi0.0: SPI transfer timed out [ +0.005210] spi_master spi0: failed to transfer one message from queue [ +0.922799] spidev spi0.0: SPI transfer timed out [ +0.012172] spi_master spi0: failed to transfer one message from queue but it is getting late here and I have not investigated why (my overlay needs tweaking for 5.11 maybe ?).
