Unfortunately I cannot answer that, since I have not been running
CURRENT for that long. Is there a way I can help to test that? I still
have my old notebook (7.1-STABLE running wpa_supplicant 0.5.10 with ipw
and rum wireless adapters). I can get the logs from that machine, too,
if that would help.

I will give it a try. Just now I merged the diffs between 0.6.8 and
0.6.9 to my /usr/src. Except for
wpa_supplicant-0.6.8/src/common/nl80211_copy.h,
wpa_supplicant-0.6.9/src/l2_packet/l2_packet_linux.c and,
wpa_supplicant-0.6.9/wpa_supplicant/Makefile
I was able to apply the diffs.

I will try this at university on Thursday or Friday and report any
success or failure here.


Thanks for the help and hints so far.
