My impression is that some of the people reporting problems have been using stock upstream kernels, so I wasn't really worried about the Ubuntu kernel (although it could be something about the default configs that Ubuntu sets up). What I was more wondering was whether there was something about userspace or default configs of Ubuntu. This isn't necessarily a *problem* per se; for examople, not that long ago some users were getting surprised when a problem showed up with an older version of the LVM2 userspace with newer upstream kernels. After a while, you learn to get super paranoid about making sure to rule out all possibilities when trying to debug problems that are only hitting a set of users. - Ted
