If you are interested in developing for the Linux kernel then I advise for you to join the kernel.org mailing-list and review their archives to see what has been discussed. All official development and kernel communication is done on kernel.org

Welcome to the community, I have already responded on your other post about merging pdf files.

I was originally thought about using imagemagik, but it would be slow. I recommend looking at the thread at http://superuser.com/questions/54041/how-to-merge-pdfs-using-imagemagick-resolution-problem , of the solutions using pdftk sounds like the easiest method to me.

I am running Slackware-current, but I don't think that matters much since the support for that chipset and EDAC module were introduced in 2007 and pushed to stable shortly after. In addition I did a huge search on the net about that board and found the minimum kernel version in the Debian HCL (http://kmuto.jp/debian/hcl/SuperMicro/X7DAL-E) which is what ubuntu is based on, so it still applies. In my search I did not find any other people reporting the same issues with the system, just a lot of hardware issues.

Have you tried swapping the HDDs and connected mobos as previously suggested? I am very curious about the outcome.

Have you verified that the SeLinux restrictions on the files in that directory are not blocking the external access?

Thank you for the response, I will try to follow up on your lead.

I have reviewed the kernel I have installed (3.7.1) and can see that the listed chipset is supported, but the EDAC is disabled on my system. Can you please point to the site where the drivers where available for Linux systems?
