hmm, says me nothing, but is it reproducible? I believe a standard kernel shouldn't have problems executing VMX instructions ...

MauryG5:
But in fact it seems strange to me too that suddenly there is a conflict between altivec and the new kernels, because it would mean that we at Power have the problem specifically ... I don't know what is happening on X86 or Arm in relation to this fact...

Confirmed then apparently, the problem is ours on Power unfortunately ...
