Hi, I recently upgraded my IBM ThinkPad X31 from 6.1-RELEASE to 6.1-STABLE after which the if_iwi(4) driver started dropping the connection at regular intervals when connected to my hostapd-based AP using WPA2 PSK CCMP.
The dmesg output with debug.iwi=4 is listed below - it fails regularly (every 3 mins or so) with the message "scan stuck" after which the adapter is reinitialized and the connection lost for some seconds. The connection drop seems to be caused by the adapter suddently entering the SCAN state. I have been unable to reproduce this problem with 6.1-RELEASE. $ uname -a FreeBSD fangorn.brixandersen.dk 6.1-STABLE FreeBSD 6.1-STABLE #2: Tue Jul 18 11:16:02 CEST 2006 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GENERIC i386 Jul 20 23:38:04 fangorn kernel: iwi0: <Intel(R) PRO/Wireless 2915ABG> mem 0xc0200000-0xc0200fff irq 11 at device 2.0 on pci2 Jul 20 23:38:04 fangorn kernel: iwi0: Ethernet address: 00:0e:35:fd:81:94 ...
