Okay, then this idea to temporarily workaround the bug did not work.
I will set up KM400, K8M800, and P4M900-based system with Lubuntu 12.04 i386 to
be able to run more experiments on my side.
I will use the latest version of the device driver code from the Git repository
for testing purposes.
Please give me several days to get this ready as I usually install multiple
installations of Ubuntu / Lubuntu on each system (i.e., Ubuntu 8.04 LTS, Ubuntu
10.04 LTS, Lubuntu 10.04, Lubuntu 12.04, etc.).
I will also try to read and understand how the device drive code works as I am
interested in fixing and improving the base code itself.
