Mike, do you think the time is right to just remove the iPath driver?With PAT now being default the driver effectively won't work with write-combining on modern kernels. Even if systems are old they likely had PAT support, when upgrading kernels PAT will work but write-combing won't on ipath.
Sorry, do you mean the driver already doesn't get WC? Or do you mean after some more pending patches are applied? Jason
