with rev 17. the systems freezes hard on my Lenovo N 500, FreeeBD 8.0 amd64, with a kernal panic after i enable rthe radio switch.

I can not obtain any dump.

It seems to work a little. But it can't hold the conenction.

I committed several changes a minute ago, which also changes a bus_dmamap_sync() call. This might fix a bunch of initialization and random firmware errors. It also prevents a deadlock condition.

for the last 14 hours, with that version, I had no connection loss, no packet loss, no LOR and no dead lock using a 5100 over a WPA connection.

Not even a backtrace?

Firmware errors re-init the driver almost completely, dropping connection is expected. So we must prevent any of this.

Let me know whether those still occur in rev20, if they do, we have to find the cause.

Well, I had a panic (at least I suppose so) after about an hour. I didn't find anything in the logs.

Let me know if that still happens with rev23. You might also want to add
Code: 
dumpdev=AUTO
to /etc/rc.conf to get a vmcore to analyse.
 
Tried rev23 but still no success. The machine paniced after about 10 minutes.

I tried this a 2nd time in the console and I didn't see a thing, it just freezes and I have to press the power button.
 
Tried it two times to get something useful. 2nd crash followed after 50s uptime.

Well it works ... sort of. At least I see no panic, but the connection transmits garbage only. I can see this with elinks, Firefox stops working at once, if I try to load something.
 
I just found out that a driver for the Intel 5300 AGN is availible. I've read the thread and I'm a little unsure on the installation. The driver that comes with 8.0-RELEASE does not load so it's clear I'll have to get it from somewhere. My machine is a DELL Latitude 6500 with the above WiFi card. I'm using a usb wifi a the moment and it would be great to be able to use the built in Intel card. Thanks for any hints :-)

Thank you!

It works fine. Had to configure the wlan0 in rc.conf, then it connected.

Thanks to bschmidt for the driver :-)

If I can provide information or other feedback, Please let me know.
 
Update! I've had two reboots since installing the iwn driver. It starts with the PC getting unresponsive, the wifi lamp/indicator flashes, it's usually on, and then the computer reboots. Another thing I've noticed is that the xfce's wavelan indicator in the beginning shows low signal strenght but after 10 - 15 minutes it's indicating full level strenght. This is without moving the computer. Any comments?

More input please. Check your /var/log/messages if there is something about a panic.

On initial connect the rate is set to 36Mbit/s after the first few packets go through the rate control algo ups it to 54Mbit/s. That is probably what you are seeing.
 
I get panics shortly after a reboot (50-60s) or sometimes after about 10 minutes. Are there any special flags to set e.g. in wpa_supplicant.conf or something else to consider?
