Adding the crashkernel parameter to your kernel boot prompt, reserving 128MB of your RAM for a recovery kernel and a small boot image. When your running kernel crashes, the recovery kernel, installed by kexec-tools, is going to generate a kernel dump, which can then be grokked by crash to generate a dump. In either case, you have a fair bit of RTFMing to do. And then after wasting all the time, you'll discover that you're not getting a useful crash in the first place.Hmmm, you paint a rosy picture ;-)
It's definitely: 1) A learning curve 2) Doable.
But if I do nothing, my choices are: 1) hope to get lucky on some future kernel update
There is precedent for that. Circa Fedora 9, or so, there were something like three or four kernel updates in a row before the kernel managed to boot succesfully on one of my machine.
