The issue can be fixed by the following upstream commit:

commit 7623eee9046015b65a1f63f6bf07ab7805c36eb4
Author: Dave Anderson <anderson@xxxxxxxxxx>
Date:   Tue May 19 10:20:04 2015 -0400

    Fix for the ARM64 page size determination on Linux 4.1 and later
    kernels.  Without the patch, the crash session fails during
    initialization with the message "crash: invalid/unsupported page
    size: 98304" on kernels with 64K pages.  On kernels with 4K pages,
    the message is "crash: invalid/unsupported page size: 6144".  In
    addition, the "-p <page-size>" command line override option
    had no effect on ARM64; that has been fixed as well.
