Comment 12 for bug 333730

I installed linux-backports-modules-jaunty(2.6.28.11.14), The kernel errors(attached) were gone as was the symptomatic performance problem. There are issues with the backports ath9k module(periodic loss of connection) which are just as trying as this....

The kernel errors, "page allocation failure", would happen very frequently until reboot. I will remove linux-backports-modules-jaunty and do more testing so I can provide more details.
