Radeon init fail and resulting cascade of UBSAN errors

I just put a Radeon 9600XT into an Athlon XP machine. I do not know if the card
is good or not, but 2D dumb framebufer works fine with radeon module. However,
init of the acceleration engine fails. I compiled my own kernel (v5.0 from git)
with UBSAN (no other debug yet) and got a cascade of UBSAN warnings and two other
errors on bootup.

A "kobject (b8a6a825): tried to init an initialized object", some UBSAN warnings
from ttm and finally a kernel read fault.

Whether or not the initial problem is hardware or software problem, the rest
seem to be our error handling bugs.
