Lots of people use it. >=20 I know and I really don't have a problem with UIO itself. The uio_pci_generic module does not export correctly, maybe you take a look on its code? My guess is, that the uio_pci_generic module isn't commonl= y used and therefore the problem wasn't reported before. --=20 Gru=C3=9F Dominic =46rankfurt Institute for Advanced Studies (FIAS) Ruth-Moufang-Stra=C3=9Fe 1 D-60438 Frankfurt am Main Germany Phone: +49 (0)
