Try calling irq_set_chip_and_handler() with handle_level_irq, rather
than irq_set_chip().  The -rt patch doesn't seem to have threadified
  the __do_IRQ() path.

The demuxer is setting itself up with set_irq_chained handler(), any
pointers on how to change to irq_set_chip_and_handler()?

No, I mean the call to set_irq_chip() in pci_pic_host_map() where it sets up the IRQs it manages, not the cascade IRQ itself.
