Hi all I have more or less recent 8-CURRENT. And I've noticed that attempt to start wireless (start of wpa_supplicatnt) when there is no wireless networks in proximity leads to hard lockup of notebook, even DDB can't be called. I have IBM T60 with: FreeBSD 8.0-CURRENT #3: Tue Jul 15 14:42:12 MSD 2008 root@vbook:/usr/obj/usr/src/sys/VBOOK ath_hal: 0.9.20.3 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413) ath0: <Atheros 5212> mem 0xedf00000-0xedf0ffff irq 17 at device 0.0 on pci3 ath0: [ITHREAD] ath0: WARNING: using obsoleted if_watchdog interface ath0: mac 10.3 phy 6.1 radio 10.2 wlan0: Ethernet address: 00:19:7d:44:44:44 Once I've noticed extremely high interrupt rate before lockup. In case when there is wireless networks around everything goes as expected. Any hints will be very appreciated. -- Vladimir B. Grebenschikov vova@fbsd.ru
