Well, I removed KDM and rebooted without it.
I use wicd instead of Network Manager because of lp:689529 so it brings up my wireless connection without requiring manual GUI actions. And this causes a nice kernel panic (retyping from the screen) :
assertion "!(sdu->cloned)" failed: file "wlc_mac80211.c", line 5129
there is also a long stack, starting from igmpv3_send_cr, going through wlc_sendpkt_mac80211, then to some AES encryptions, then to minstrel_get_rate - and ending with osl_assert/snprintf/panic
