Actually the threads above are for MSI, not MWI, which would be set with pci_set_mwi() not pci_disable_msi(). MWI is for enabling memory write invalidate. I guess we never had the MWI discussion then for ath5k, Either way I'm reluctant to enable it and was actually considering simplifying the the PCI cache line size thing on ath/ath5k/ath9k. Will send an RFC.
