This is a continuation of issue 1785: http://bugs.dragonflybsd.org/issue1785 I'm now running with BUS_DMA_NOWAIT as Joe Talbott told me. See attached patch. My problem right now is when I fool around with wpa_supplicant. On a second use it panics. zoidberg# ifconfig wlan0 create wlandev ral0 up ral0: need multicast update callback zoidberg# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf Trying to associate with 00:1d:7e:f0:fd:1f (SSID='moh' freq=2422 MHz) Associated with 00:1d:7e:f0:fd:1f WPA: Key negotiation completed with 00:1d:7e:f0:fd:1f [PTK=CCMP GTK=CCMP] CTRL-EVENT-CONNECTED - Connection to 00:1d:7e:f0:fd:1f completed (auth) [id=0 id_str=] ^C CTRL-EVENT-TERMINATING - signal 2 received ioctl[SIOCS80211, op 20, len 7]: Can't assign requested address ioctl[SIOCS80211, op 26, arg 0x0]: Operation not supported Failed to disable WPA in the driver. ioctl[SIOCS80211, op 26, arg 0x0]: Operation not supported ELOOP: remaining socket: sock=4 eloop_data=0x283c0080 user_data=0x28400070 handler=0x806518b zoidberg# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf *panic* Same if I set it up in rc.conf and do a 'rcrestart netif' The panic looks like this: Unread portion of the kernel message buffer: Fatal trap 12: page fault while in kernel mode fault virtual address = 0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc029fcfc stack pointer = 0x10:0xd7c78cb8 frame pointer = 0x10:0xd7c78d08 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = Idle current thread = pri 60 (CRIT) kernel: type 12 trap, code=0 panic: from debugger Fatal trap 3: breakpoint instruction fault while in kernel mode instruction pointer = 0x8:0xc05517f8 stack pointer = 0x10:0xd7c78ac8 frame pointer = 0x10:0xd7c78ad0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, IOPL = 0 current process = Idle current thread = pri 92 (CRIT) panic: from debugger Uptime: 3m49s Physical memory: 2038 MB Dumping 159 MB: 144 128 112 96 80 64 48 32 16 Reading symbols from /boot/modules/vesa.ko...done.
