Hi, Im running FreeBSD current: FreeBSD nereid 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r265628: Thu May 8 08:05:37 UTC 2014 root@grind.freebsd.org:/usr/obj/usr/src/sys/VT amd64 on Asus Zenbook UX32VD. My wireless network works ok, however from time to time I need to restart the netif service since my link does not work anymore. After restart everything is ok. The device is: Wifi: Intel Centrino Advanced-N 6235. Sometimes Im able to see something like: iwn0: iwn_scan: called whilst scanning! iwn0: iwn_intr: fatal firmware error firmware error log: error type = "UNKNOWN" (0x0000198A) program counter = 0x00015920 source line = 0x000001DC error data = 0x0000029600000000 branch link = 0x0001591000015910 interrupt link = 0x0000DBEA00000000 time = 2479833477 driver status: tx ring 0: qid=0 cur=14 queued=0 tx ring 1: qid=1 cur=0 queued=0 tx ring 2: qid=2 cur=0 queued=0 tx ring 3: qid=3 cur=19 queued=0 tx ring 4: qid=4 cur=0 queued=0 tx ring 5: qid=5 cur=0 queued=0 tx ring 6: qid=6 cur=0 queued=0 tx ring 7: qid=7 cur=0 queued=0 tx ring 8: qid=8 cur=0 queued=0 tx ring 9: qid=9 cur=1 queued=0 tx ring 10: qid=10 cur=0 queued=0 tx ring 11: qid=11 cur=0 queued=0 tx ring 12: qid=12 cur=0 queued=0 tx ring 13: qid=13 cur=0 queued=0 tx ring 14: qid=14 cur=0 queued=0 tx ring 15: qid=15 cur=0 queued=0 tx ring 16: qid=16 cur=0 queued=0 tx ring 17: qid=17 cur=0 queued=0 tx ring 18: qid=18 cur=0 queued=0 tx ring 19: qid=19 cur=0 queued=0 rx ring: cur=24 After restarting the networking service everything is back to normal. ifa_del_loopback_route: deletion failed: 3 wlan0: link state changed to DOWN wlan0: Ethernet address: c4:85:08:a3:4e:09 wlan0: link state changed to UP Is iwn firmware the issue here, or a bug in iwn driver ?
