Doporucuju k tehle problematice pozorne procist archiv mailinglistu freebsd-mobile@, kde se zrovna nedavno (v breznu) tohle resilo: ------- citace ------- btw, according to an older post, "wpi error: bus_dmamem_alloc failed to align memory properly" is not really a big deal. I used to get those errors (you will see this in the configs I pointed you to above) but wpi worked anyway. The latest patches that have been floating around on freebsd-net@ solve the problem (and a host of others, too). I don't know if they've been MFCd back to 7.0 yet but they will be. http://people.freebsd.org/~thompsa/wpi_releng7.diff ------- citace ------- Mirek -- FreeBSD mailing list (users-l@freebsd.cz) http://www.freebsd.cz/listserv/listinfo/users-l
