Hi Dejin, > Use the correct name of device-managed function to alloc irq vectors, > the pcim_alloc_irq_vectors() function, a explicit device-managed version > of pci_alloc_irq_vectors(). [...] It would be "IRQ" in the sentence above. Perhaps the "Use the new function pcim_alloc_irq_vectors() to allocate IRQ vectors ..." would read a little better - generally, the above sentence could be improved. You might also want to add a more details about why to use this new function instead of the previous one, etc. Krzysztof
