Hi Scott, Please give more detail about the issue if you can. I would really like to understand how the changeset negatively impacted you in order to fix the issue. I have used this changeset on headless machines (so no keyboard or mouse entropy) with both GENERIC kernel and a kernel without RANDOM. For kernel without RANDOM I even waited until I had a login prompt to load the ko's in order to test having no /dev/random until fully multi-user. -- -- David (obrien@NUXI.org)
