I'm not sure why an arm-targeted gdb would not complain about loading a 
x86-target vmlinux image. That sounds off.

You could try with an older arm gdb to see if it works fine. If it does 
and the latest version doesn't, then we may need to investigate it.

I checked the code and the truncation message is a result of the 
debugging stub sending less bytes than GDB expects for the register set.

Just to confirm, does your arm target have floating point registers?
