0x44 is a REX prefix in 64-bit mode, so somehow ksymoops got it
wrong and gave you an i386-mode decode instead of 64-bit mode.
Did you run it on a i386 machine and it assumed i386? Maybe you
need to use "-a x86-64"?  (I can't make it work on my setup.)

So it's really "mov (%r8),%ebp" if I am reading the manual right.

I don't know what ksymoops's problem is.  I noticed that without `-a' it
gave x86 code so I gave it `-a i386:x86-64' and didn't bother to read the
output ;) Seems that nothing I can do will persuade it to not treat this as
i386 code.
