I ran the Task h1_0978.80_S5R4__1226_S5R5a (WU# 48475297) on our G5 machine using the official AltiVec App einstein_S5R5_7.01_powerpc-apple-darwin_1. I got a result that according to the validator was consistent with the two valid results of this workunit and significantly different from the invalid one of the machine in question. Looks like a problem on the machine (heat?).
