Still the same, but they are now on different irqs. I noticed however > that my drm0 doesn't get set up with acpi interrupt routing turned on.
Hmm, looks like its irq setting up is hosed somewhere else. drm device itself is attached. As far as I understand the drm code, bus_setup_intr is triggered by user space program like Xorg, but there are some precondition check before bus_setup_intr is called. Please set hw.dri.debug=1 (sysctl) and give me the output of vmstat -iv and dmesg, after you started Xorg.
