KS2012: Distributions and upstream

Quite. Note that if you have some module that you rely on that you need to use even when doing bug reproduction, but that is not included in the distro kernel, you can often take the distro config and kernel source and enable and compile that module, then load the module atop the distro kernel. This will usually work (modulo only those strange cases where enabling a module will also change code in the core kernel). (It's probably best to mention that you did this to the support people you're talking to, just in case it did break something, but I doubt that this approach will rouse too many hackles.)
