It also sometimes happens when when doing a ping flood (ping -s 1400 -f). However, data reception works just fine, including promiscuous mode. The system is running 4.6-RELEASE. The card is operating in infrastructure mode, and it gets correctly associated to a base station. WEP-128 bit is enabled. These are the relevant kernel messages: >>> D-Link DWL-650 card inserted <<< pcic0: Event mask 0x2 pcic0: Event mask 0x2 pcic0: Event mask 0x2 pcic0: Event mask 0x2 pcic0: Event mask 0x6 pcic0: Autodetected 3.3V card pccard: card inserted, slot 0 pcic0: reset 1 int is 10 stat is 6d pcic0: reset 2 int is 70 stat is 4d pcic0: reset 3 int is 70 stat is 6d pcic: I/O win 0 flags 15 240-27f wi0: Forcing IRQ to 11 pcic: I/O win 0 flags 5 240-27f wi0 at port 0x240-0x27f irq 11 flags 0x10000 slot 0 on pccard0 pcic: I/O win 0 flags 15 240-27f wi0: Forcing IRQ to 11 wi0: 802.11 address: 00:05:5d:5c:24:00 wi0: using RF:PRISM2.5 MAC:ISL3873 wi0: Intersil Firmware: Primary 1.00.07, Station 1.03.05 wi0: wi_has_wep = 1 bpf: wi0 attached pcic0: Event mask 0x9 >>> File transmission is started; after ~200-300 KB... <<< wi0: watchdog timeout wi0: timeout in wi_cmd 0x0002; event status 0x8000 wi0: timeout in wi_cmd 0x0000; event status 0x8000 wi0: wi_cmd: busy bit won't clear. wi0: wi_cmd: busy bit won't clear. wi0: init failed wi0: wi_cmd: busy bit won't clear. wi0: wi_cmd: busy bit won't clear. wi0: wi_cmd: busy bit won't clear. >>> and so on... <<< The system enters an quasi-frozen state, until I remove the card: about 15-20 seconds later the card extraction is detected and the system resumes its normal operation. I tried to set hw.pcic.intr_path=1 to no avail. Other PCMCIA cards work just fine (the machine is a Dell Inspiron 3700). >How-To-Repeat: 1. Get and insert a D-Link DWL-650 card into your laptop ;-) 2. Wait for it to be associated to a base station. 3. Send a large file (using ftp or scp, for example) to another machine. >Fix: Unknown. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
