Description

I've got permanent kernel panic and reboot with intel wireless 4965 minipcie card in WAN infrastructure mode when wpa is activated.

It seems to me the reason is absence of timeout after wpa_supplicant is started, at least the patch below helped me

unset($wlcmd_args, $wlcmd);

- sleep(1);
/* execute hostapd and wpa_supplicant if required in shell */
mwexec("/bin/sh {$g['tmp_path']}/" . escapeshellarg($if) . "_setup.sh");
+ sleep(1);

return 0;

Yes, moving the sleep(1) line from above to below the wpa_supplicant loading line resolved the issue.

I now have pfsense using WiFi as the WLAN link.

Considering all big FreeBSD changes since 2.2.x I must ask. Is it still happening on current versions?
