Can you supply some more information? It's impossible to tell what is
wrong from the information you supply. 

E.g, do you use the GENERIC kernel, or did you build your own. If so,
what does your kernel config look like?

Can you show dmesg output from when a umass device is plugged in?

If you get a kernel panic, what does it say?

Is there anything in the logfiles?

I've been using umass devices from 5.4 onwards on amd64 and i386 without
problems.
