That is probably the diag308_set_works detection code that is called
early in the boot process:
void __init ipl_update_parameters(void)
{
int rc;
rc = diag308(DIAG308_STORE, &ipl_block);
if ((rc == DIAG308_RC_OK) || (rc == DIAG308_RC_NOCONFIG))
diag308_set_works = 1;
}
I did not look at the hercules code but I guess that this detection code
triggers a reboot. It does match the symptom ..
