M. --- a/drivers/of/irq.c +++ b/drivers/of/irq.c @@ -282,8 +282,10 @@ int of_irq_parse_raw(const __be32 *addr, struct of_phandle_args *out_irq) oldimap = imap; imap = of_irq_parse_imap_parent(oldimap, imaplen, out_irq); - if (!imap) - goto fail; + if (!imap) { + match = 0; + break; + } match &= of_device_is_available(out_irq->np); if (match) This may not be the final workaround even if it solves your boot problem, but will at least give us a hint at what is going wrong. I have the fuzzy feeling that we may be able to lob this broken system as part of the of_irq_imap_abusers[] array, which would solve things pretty "neatly". M. - - - - We tested this patch yesterday and it solves the boot problem. Thanks - - - - I am sorry our tester was wrong and has reported, that this kernel doesn’t boot.
