In Feisty, the driver (compiled from their SF.net project page, version 1.2.3) worked fine without any major problems. Now, in Gutsy, after upgrading to linux-ubuntu-modules version 2.6.22-13.33, the driver is included in the Ubuntu distribution. When the et131x module is loaded, I experience the process ksoftirqd to be busy quite often, producing heat and draining my battery faster. The solution is to unload the module if I don't need wired ethernet, but of course it would be cool to have ethernet and not haing 25-20% of your cpu eaten up by the kernel. The exact same problem exists with a self-compiled kernel module with the patch found at http://sourceforge.net/tracker/index.php?func=detail&aid=1709009&group_id=179406&atid=889025 . Unfortunately, I don't know how to debug this problem or narrow it down. I suspect the driver not being compatible with the new kernel's tickless interface, but obviously I'm not sure about this.
