I ran the testcase on my older G5 today with:
cpu : PPC970, altivec supported
revision : 2.2 (pvr 0039 0202)
and it also failed after a few iterations. This was with
2.6.25-0.121.rc5.git4.fc9 as the kernel, which is fairly close to mainline. At the least, this doesn't seem to be 970FX related. I'll try building a vanilla 2.6.25-rc7 later this evening to see if that makes a difference.
