Bug Description
I have a LG T1 Express Dual laptop with an Agere et131x ethernet adapter. 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-
The exact same problem exists with a self-compiled kernel module with the patch found at http://
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.
I can confirm this bug - I have also a LG T1 and after upgrading to Gutsy the process ksoftirqd coused permamantly 15-30% cpu load. After removing the module et131x there is no more cpu load of ksoftirqd.
