Thread-topic: Bug #1359980 - Unable to perform a full kernel crash on Ubuntu 14.10

Hi Mark,

I have a bit more clarity now on this bug we discussed yesterday.  Aside from documentation there is actually a change needed in the kexec-tools package.  By default the package adds "crashkernel=384M-:128M" to the kernel parameters, but this does not seem to work on Hyper-V.  The request in this bug report is to change increase the amount of memory - so change the parameter to "crashkernel=384M-:256M," at least on Hyper-V.

Thanks,
