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.
