Sorry I have no specific help to offer for this at this time, but I am starting to think that the WPA not working under 2.6.31.6 is also a timing problem - see https://savannah.nongnu.org/bugs/?28289 "gNewSense GNU/Linux - Bugs: WPA doesn't work on yeeloong under 2.6.31.6-libre1 linux" Has anyone had WPA work under 2.6.31.6 or later on the yeeloong? Any workarounds you had to employ (other than dealing with the rfkill stuff)? -- Daniel JB Clark | Sys Admin, Free Software Foundation pobox.com/~dclark | http://www.fsf.org/about/staff#danny _______________________________________________ gNewSense-dev mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/gnewsense-dev
