I updated my machine over the weekend to FreeBSD X220.alogt.com 10.0-STABLE FreeBSD 10.0-STABLE #38 r267699: Sun Jun 22 16:32:07 WITA 2014 er...@x220.alogt.com:/usr/obj/usr/src/sys/X220 amd64 I started it only a single time with IPV6 enabled and the machine crashed again. It looked to me that it was the same location but I did not verify it. I run the machine since then with IPV4 only and did not have any trouble. Maybe a word to the timezone. It seems that we are 12h apart. So, early morning and early evening would be the best pairing for us.

Ok, it's a null pointer dereference (based on the address you posted) and it's ipv6 related. That's .. odd.

When I disable ipv6, it all works fine. I did several reboots without a problem. To make this a bit more complicated, if I use only em0, the machine starts normal. When I use iwn0 alone or together with lagg0 and em0, the machine crashes during the boot process. The crashes only happen when IPV6 is enabled in rc.conf.

The only problem is that it also works with DLink but only randomly. So, it still could have been that I was just always lucky when connecting to the ProLink access point I have. As the DLink is not mine, I am not even able to access its administration interface.

Re: iwn0 hangs randomly when starting the machine
Coexistence is to deal with the fact that a 40MHz channel may overlap a 20MHz-only AP in the extension channel. If the AP finds a 20MHz AP in the extension channel (ie, the other half of its 40MHz) channel then it'll flip itself to 20MHz. If it determines it isn't there any more, it'll flip the BSS to the 40MHz channel. Now, why the hell it's causing the connection to fail? I have no idea. can someone file a PR that says it's all busted with 40MHz coxistence enabled? We can then start debugging from that position. -a ___ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"

On my own router, a ProLink if I remember right, I can only switch between 20 and 40 MHz channel with but I cannot have both. I wonder why the router needs the coexistence. Is it to communicate with other routers to find free channels?

Hi, 20/40 coex is supposed to be some corner of the spec that notices whether there's a 20mhz only AP on the extension channel and if so, flip everyone over to 20MHz.

I've been experimenting with routers and such ... and I found something *interesting* with iwn(4). On my dlink dir825-C1 I have a channel option "HT20/40 Coexistence". If I disable this, I cannot associate in the 2.4G hz channel at all. I don't know if this is clueful, but it seems to mirror my problems at work. Associates for a moment and then drops. Since I don't know what this really means, I thought I'd chuck it over here and see if its meaningful. sean signature.asc Description: This is a digitally signed message part

iwn0 hangs randomly when starting the machine
Hi, since I upgraded to r263767, I have the following problem: Wireless does not start all the while. When it does not start, it hangs then forever. wpa_supplicant's state in top is then '-'. If I start wpa_supplicant by hand, it will hang and it cannot be stopped by control C. The light indicating that wireless is up is never on in this case. Rebooting the machine solves the problem. I did not find any other way to solve as the wireless related commands will hang. When the wireless network comes up, I can work just normal.
