Can someone please describe what was changed? Just sending SIOCGIWSCAN events more frequently? I have not seen any problems with this in my tests (though, mainly with madwifi-ng). Is the broken case available in one of the kernel trees? 2.6.16? wireless-2.6? (i.e., where can I get the exact version of ipw2200 driver that is expected to show incorrect behavior)? > Jouni was notified, but did not really answer to that bug report. > Then, the ipw maintainers commited the following patch to ipw > that fix or workaround that issue : > > http://marc.theaimsgroup.com/?l=linux-netdev&m=114492056522667&w=2 Hmm.. I don't remember having seen that report from Bill Moss.. How was I notified? ;-) The patch here seems to be moving ipw_disassociate() call, so it is not obviously clear from that what the impact on behavior is. I can try to reproduce this, but I would like to know what version to test with in order to avoid any possible workarounds from hiding the issue. -- Jouni Malinen PGP id EFC895FA
