Great news, btw, are you aware of WPA problems with the iwi(4) driver? I had no problems and good performance early this year, but since March or so, the driver gets stuck regularly. For example I can no longer boot up with if_iwi loaded and the WPA bits in rc.conf, as the immediate startup of wpa_supplicant will somehow wedge things (I have a couple of traces for this): ifconfig wlan0 down will get stuck, killing wpa_supplicant is no longer possible, etc. What works for me (please don't laugh): - boot up without if_iwi loaded - disable wlan radio using hotkey - load if_iwi, devd will automatically start wpa_supplicant - wpa_supplicant will eventually (1-2 min) associate with my ath(4) based AP - turn on radio per hotkey - check ifconfig wlan0 to see if everything is alright - ifconfig lagg0 laggport wlan0 for wired/wireless roaming. Here's a trace of when 'ifconfig wlan0 down' was stuck, too bad the trace for wpa_supplicant doesn't show up in the textdump Tracing command ifconfig pid 1894 tid 100121 td 0xc4d76c30 sched_switch(c4d76c30,0,104,191,3593fa53,...) at sched_switch+0x2fc mi_switch(104,0,c092b242,1eb,5c,...) at mi_switch+0x200 sleepq_switch(c4d76c30,0,c092b242,260,0,...) at sleepq_switch+0x15f sleepq_wait(c41862d8,5c,c091c518,0,0,...) at sleepq_wait+0x63 _sleep(c41862d8,c3f02494,5c,c091c518,0,...) at _sleep+0x365 taskqueue_drain(c3f02480,c41862d8,48d,c0935b10,fb51cab8,...) at taskqueue_drain+0xf5 ieee80211_vap_detach(c4186000,fb51cae4,0,fb51cacc,c06bac77,...) at ieee80211_vap_detach+0x78 iwi_vap_delete(c4186000,fb51cae4,c0694457,c413f000,c413f000,...) at iwi_vap_delete+0x12 wlan_clone_destroy(c413f000,c413f000,c413f000,c413f000,fb51cb10,...) at wlan_clone_destroy+0x17 ifc_simple_destroy(c099c260,c413f000,c09362cc,105,c099c290,...) at ifc_simple_destroy+0x27 if_clone_destroyif(c099c260,c413f000,c09362cc,e0,c42225c0,...) at if_clone_destroyif+0x12e if_clone_destroy(c42225c0,19c,c0954c7d,c091ead3,3,...) at if_clone_destroy+0xa2 ifioctl(c3c4f670,80206979,c42225c0,c4d76c30,c4415100,...) at ifioctl+0x476 soo_ioctl(c44433b8,80206979,c42225c0,c44b2700,c4d76c30,...) at soo_ioctl+0x40f kern_ioctl(c4d76c30,3,80206979,c42225c0,6230b0,...) at kern_ioctl+0x1fd ioctl(c4d76c30,fb51ccf8,c09615aa,c09492c0,c4d6d2a8,...) at ioctl+0x134 syscall(fb51cd38) at syscall+0x220 Xint0x80_syscall() at Xint0x80_syscall+0x20 --- syscall (54, FreeBSD ELF32, ioctl), eip = 0x281cbb13, esp = 0xbfbfe44c, ebp = 0xbfbfe468 --- Uli
