My laptop with ndis driver for BCM4313 NIC crashes periodically during the heavy traffic with this kernel stack: KDB: stack backtrace: #0 0xffffffff809906f0 at kdb_backtrace+0x60 #1 0xffffffff80953436 at vpanic+0x126 #2 0xffffffff80953303 at panic+0x43 #3 0xffffffff80d5bedb at trap_fatal+0x36b #4 0xffffffff80d5c1dd at trap_pfault+0x2ed #5 0xffffffff80d5b85a at trap+0x47a #6 0xffffffff80d4192c at calltrap+0x8 #7 0xffffffff82098a1d at ndis_start+0x49d #8 0xfffff8000438f0ce at dmapbase+0x438f0ce #9 0xffffffff82083aa9 at x86_64_call2+0x9 #10 0xffffffff8091c5fa at fork_exit+0x9a #11 0xffffffff80d41e6e at fork_trampoline+0xe Crashes happen when wifi connection is established, and wpa_supplicant from ports is running with a single network in wpa_supplicant.conf. I am not sure why ndis_start is called. It is possible that wpa_supplicant decides to bring the interface down and up for some reason. FreeBSD 10.3 Yuri
