Sorry for the long delay in my response. This seems like a serious but not actually grave issue, since the core dump does actually exist (even though you have to interrupt the dmesg extraction). crash identifies the dump as a partial dump because we explicitly ignore zero pages and userspace pages. Within crash, you should be able to use the 'log' command to get the most recent log messages before the crash...assuming crash doesn't break in the same way makedumpfile does. I will try to reproduce this, but I worry the problem might be somewhat specific either to your crash or some other part of your configuration. Would you feel comfortable making the vmcore available to me? It would also help to know the exact kernel version, and access to a dbg package if it's not a stock kernel.
