I investigated the problem a bit when I had trouble with a self-compiled
glibc a year or so ago. IIRC, I found bug in the memset code, not in the
chip. The code was just wrong for cache line sizes not equal to 32. So
memset.S is good for 60x series (PQII included) but for 8xx it fails. We
use dcbX instructions in some kernel drivers and since we never had any
problems with those drivers I'm a bit surprised to hear that all 8xx
chips have got that bug.
