This appears to be because it is truncating the high address given as input to 32-bits as part of the stage 1 translation, and so the stage 2 translation fails because the input IPA is invalid. I have reported this as a potential model bug because stage 1 translation is not enabled (SCTLR_EL1.M == 0) and therefore IPA<0:47> is supposed to be equal to VA<0:47>.
