RS232-RS485-CAN-Board erros

I've got this marvelous pi hat RS232-RS485-CAN-Board With this config: enable_uart=1 kernel=u-boot.bin [all] device_tree=bcm2711-rpi-4-b.dtb dtparam=spi=on dtoverlay=i2c0 dtoverlay=spi1-3cs dtoverlay=sc16is752-spi1,int_pin=25 dtoverlay=mcp2515,spi0-0,oscillator=16000000,interrupt=23 dtoverlay=mcp251xfd,spi0-1,interrupt=24 And both can interfaces won't show at the same time, not sure why When I comment out one of them the other show's up in the ifconfig Additionally, the mcp2515 works but the mcp251xfd fails with this: [ 52.157476] IPv6: ADDRCONF(NETDEV_CHANGE): can0: link becomes ready [ 52.167715] NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!!
