Just read in the release notes that it is because pre4.4 kernels where only routing via ISA whereas 4.4 and newer default to use pci routing (but support ISA routing as well). I think its nice to have it an option, but I think ISA routing should maybe be default for generic kernels (it causes less troubles it seems). But oh well, it works now and if this option is present in all successor kernels I shall be fine :) Sincerely, Andreas To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the messagehome | help
