For the past one month I am facing random freezes on my Asus 1005px EEEpc. Here I have filed a public bug report on launchpad. There I was informed that it is a duplicate of an already reported bug. I was adviced not to shift to ubuntu 10.10 netbook edition in an answer to the question I posted here. By turning off the network services, wireless and also after some tests, I strongly believe that it is caused by the wireless driver. The wireless card is: Atheros AR2427. I have to install the drivers manually by executing this command:

sudo apt-get install linux-backports-modules-wireless-maverick-generic

There is no response on the bug report page. The issue has become a big pain. Many times I have lost very imprortant work because of that bug. Please suggest some solution. If there is no solution, atleast tell me how can I avoid system freezes.

If possible in the future avoid Atheros, I have a long story of issues with those wifi cards. – João Pinto Nov 6 '10 at 21:43
Yes you are right. I installed archlinux to find out if the issue was specific to ubuntu. When the wireless was not being used, archlinux performed very well. The moment I set up a ad-hoc network, same freeze occured on it too. – nixnotwin Nov 10 '10 at 2:27

Unfortunately it looks like that card isn't supported yet, but you could try these instructions.

Thanks for the link. I compiled and installed a recent version of the driver. The system remained up for few hours without going into a freeze (which hasn't happened before).I will do few more tests. I hope it will work. – nixnotwin Nov 10 '10 at 2:37
Yes it solved the issue. So the driver available from apt has bugs. – nixnotwin Nov 14 '10 at 1:59
