Comment 37 for bug 943880

Hi Maarten,

I installed the synaptics driver, and rebooted into the standard
kernel, and the standard kernel was really unstable so I rebooted back
into mainstream kernel. I'm a bit concerned about the security
implications of running an old mainstream kernel, but at least the
mainstream kernel is stable. I'm using the same synaptics driver in
both by the way, since it's the same system, and my touchpad works
fine in mainstream.

Perhaps there is something in one of the modules that is part of the
Ubuntu kernel that is not included in the mainstream kernel that is
causing issues? For example, in the mainstream kernel, I can't run
vmware, and there is no ipv6, and app-armor support is significantly
reduced, and I imagine there are some other modules in the Ubuntu
kernel that are not part of the mainstream kernel?

Hugh
