Otherwise Dave Anderson is pretty good about > keeping crash running across multiple kernels. Only slightly patched. But they are definitely kernels I have built myself. It might just be a logistics problem where if I want to use crash I need to upgrade it when I upgrade my kernels. I got frustrated a while ago trying to get something out of crash (and I'm afraid it shows), and I have just gone to extracting the dmesg. Which gives me all of the information I generally have time to process.
