Thanks Orran.
A little cscope'ing reveals, arch/powerpc/papr/xlate.c:
  __init_papr_hcall(H_READ, not_yet);

  static void not_yet(struct cpu_user_regs *regs)
  {
      printk("not implemented yet: 0x%lx\n", regs->gprs[3]);
      for (;;);
  }

Obviously not_yet() was written before we had a proper panic() and  
before we "de-synchronized" console.
Linux does not use H_READ anymore, but we should still supported,  
I'll get on that now, tho I'll need your help to test.
Any idea why libOS is using it?
