Hello All there, I have got a shiny new Sony Vaio VGN-FS415E, installed FBSD6, (FreeBSD 6.0-RELEASE-p4). For wireless connection there is built in an Atheros 5212 chip. I configured the kernel conf file to include all the atheros modules according to the man ath: device ath device ath_hal device ath_rate_onoe, all works well until the machine is to be shutdown. When I enter halt -p, or reboot, the machine starts to shut down, but stops, after the uptime message is displayed. Nothing more happens, I have to manually switch off the machine. The next time I switch on the machine, the oss sound will crash the machine. I did remember, that I had no problem to shut down the machine when the ath modules were not used, so I cleared the ath modules from the kernel conf file and did include if_ath into the loader.conf. Again, all is going well until shutdown. Same bad behaviour. Then I tried to manually unload the ath modules, only ath_rate module can be unloaded, ath_hal gives device busy, and trying to unload the if_ath will freeze the machine. I confirmed that the Atheros 5211 is working well, 5212 give those problems. Does anybody have any idea how to unload the if_ath module? Thank you! Andreas
