Well ... Linux 4.4.154 as expected.
You probably should give this a try:

to finally upgrade to Linux 5.10
Best,

I have a Raxda rockpi with waveshare 485 can Hat.
there are strange issues with the can-bus.
I need it to get it going (it's an HMI of a machine I am building)
I have posted my test result at Raxda forum
https://forum.radxa.com/t/rockpi-4b-canbus-fault/9784
Can you please post the output of
ip -details link show
and
uname -a
?
I searched a bit on rockpi 4b and found these images:

That's pretty old stuff and the mcp251x/SPI combo was not really
reliable in those old kernels IIRC ...
all hardware runs fine on raspberry 3b
Where you likely used a more recent kernel too ;-)
Best regards,
Oliver
