[SOLVED] 2.6.35-ARCH freezes when bringing up wireless card (AR9285)
I'm trying out Arch for the first time and have run into a problem. When I try bringing up my wireless card (ifconfig wlan0 up) my computer freezes. The only thing I can do is forcefully reboot it by holding the power button down.
My wireless card:
[nikosapi@nikosapi-laptop ~]$ lspci | grep Wireless
04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)Kernel version:
[nikosapi@nikosapi-laptop ~]$ uname -a
Linux nikosapi-laptop 2.6.35-ARCH #1 SMP PREEMPT Fri Aug 27 16:22:18 UTC 2010 i686 AMD Athlon(tm) Processor L110 AuthenticAMD GNU/LinuIt used to work fine in all the other distros I've used in the past (Ubuntu, Fedora, etc) so it's definitely a regression. My kernel logs show nothing, and I can't seem to find any similar reports. What can I do to further debug this problem?

Can you post the output of lsmod?

With pleasure 
The wireless card uses the ath9k driver if that's what you're looking for.

I was just trying to see if you had ath9k loaded. 
What you are experiencing seems to be a known problem:
http://www.spinics.net/lists/linux-wire … 54555.html
I'm guessing that the problem lies with your kernel or net-tools (ifconfig).
Have you updated net-tools lately?
cat /var/log/pacman.log | grep net-toolsTry to test different factors each time, such as downgrading the kernel but leaving net-tools the same, downgrading net-tools but leaving the kernel the same, etc.

Awesome, my google-fu is weak apparently.
I just did a net-install a few hours ago so I assume I have the latest net-tools:
[2010-09-03 13:40] installed net-tools (1.60-14)I'll try downgrading the kernel first and let you know how it goes, thanks!

I was pointing out that to show you that just because a package is in the official repos doesn't mean it will work for you.

Re: [SOLVED] 2.6.35-ARCH freezes when bringing up wireless card (AR9285)
I tried a bunch of stuff and I'm glad to report that it works now!
First I tried downgrading to the first kernel in .35 series (I went from 2.6.35.4 down to 2.6.35.1) and the problem persisted. Then I went down to the last .34 kernel (2.6.34.3) available from an arch testing mirror. I was quite happy to see that the .34 kernel did the trick. I didn't stop there, I upgraded back to 2.6.35.4 and then got the compat-wireless drivers from 2010-08-21 and that also worked. I went with a non-current version of compat-wireless because it was what the guy used in the thread you linked to.
Anyway, it works now, thank you. Should I report this on the bug tracker?

I'm glad to hear it! If you think you have sufficient information and have nailed it down to the kernel (which it sounds like you have), then I don't see the harm in reporting it if it hasn't been already.

Awesome. I guess that would make this thread solved, although you had to downgrade your kernel. If it is, could you please prepend [SOLVED] to the title by editing the first post?
