| |
The specific case I am encountering is kdump under Xen with a 64 bit hypervisor and 32 bit kernel/userspace. The dump created is a 64 bit due to the hypervisor but the dump kernel is 32 bit to match the domain 0 kernel.
It's possibly less likely to be useful in a purely native scenario but I see no reason to disallow it.
