Comment 29 for bug 356768

Allright kids I'm pretty sure this is an interrupt thing with atk5k. My Atheros-based PCI wireless card has always sucked pretty hard, but upon installing a fresh copy of Ubuntu 9.10 (Karmic Koala) , I'm getting random system hangs. I never got those with my old crappy copy of Ubuntu 8.x. But now EVERYTHING locks up, the capslock/numlock light starts blinking, mocking me...no mouse, no keyboard... and worst of all my Smiths mp3s stop playing, and I have to stop emo crying long enough to power cycle the machine. Needless to say, I cannot live like this, not when I'm trying to develop under Sun VirtualBox.

I'm pretty sure its ath5k somehow ... check out this kern.log. Crash occurred around Mar 14 20:18.

#Gnome segfaults like two hours previous. Big surprise there. Whatevs.

#Nothing for two hours

#Then this "ath5k" unsupported jumbo thing. Sometimes its other ath5k related messages (noise calibration floor timeout). But always a crash within a few minutes proximity (<10mins).

Anyway, I'm downloading the kernel sources right now, I'm going to patch this shit manually since its been going on since last April 2009 at least, if not longer.

Downloading
package: linux-source-2.6.31

and I'm going to attempt to manual patch these crap ath5k drivers with vi, then recompile the modules. I'll let you know how it goes.

I will be manually adding the ten necessary lines to the ath5k driver sources from Bob Copeland's patch found here:
http://bugzilla.kernel.org/attachment.cgi?id=19574

Naturally I will be using vi on a transparent xterm.

For the curious, here's system info:
