Actually, it's 0xD. From the kernel's perspective the mask has been updated (and I even stuck a printk into set_msi_irq_affinity to verify that the writes are happening) but ... the hardware doesn't seem to reflect this. I also tried putting read_msi_msg right afterwards to compare contents, though it complained about all the MSIs _except_ for 4341. (Of course, I could just be way off on the effectiveness of that.) --D
