If fixed your issues about a month or two ago. Either use wpa_supplicant 0.6.4 and a 2.6.26 kernel, or else grab the following patches and apply locally: wpa_supplicant (committed to 0.6.x): [PATCH] wpa_supplicant: give adhoc associations a bit more time [PATCH v2] wext: handle mode switches correctly for mac80211 kernel (SHA1s from wireless-testing.git, both in 2.6.26): 872ba53395b2a8be08c3ea2d39e225e5b4a8cb40 mac80211: decrease IBSS creation latency 507b06d0622480f8026d49a94f86068bb0fd6ed6 mac80211: send association event on IBSS create You'd need to backport the wpa_supplicant patches to 0.5.x, or else poke Jouni and maybe he'll backport them for you. I do want to get them into 0.5.x as well.
