[Bug 356768] Re: ath5k driver hangs periodically, please include trivial patch in kernel

[shamwow]

Hm okay well I went away for a few days, came back, box was still
running stable.  I started checking my email and within 5 minutes I had
a kernel panic (flashing numlock lights etc)

Here's the kern.log snapshot

So I have no idea what's going on, I suppose I'll just upgrade and recompile the kernel.  I still think it's some instability problem in ath5k, there is probably a missing sanity check elsewhere in the code during wireless access point communication / reassociation.  Either that or the kernel panic has something to do with graphics (it was stable until I came back and started surfing the internet and moving the mouse).  Thanks Luis I'll probably upgrade the kernel, but Ubuntu 9.10 was the latest release so I blame them ! hah

I will post here if I solve the stability issue.  The patch to ath5k has
helped but not solved the problem. Now its stable for 96hours instead of
24 hours.
