Re: [Crash-utility] 4.8.0-rc5+: crash: invalid kernel virtual address: 0 type: "read_string characters"

Hello Cai, You are using crash-7.1.5-1.el7, but this issue has been fixed upstream in a patch that is queued for crash-7.1.6: https://github.com/crash-utility/crash/commit/7136bf8495948cb059e5595b850... commit 7136bf8495948cb059e5595b8503f8ae37019fa1 Author: Dave Anderson <anderson(a)redhat.com&gt; Date: Thu May 19 14:01:19 2016 -0400 Fix for Linux commit edf14cdbf9a0e5ab52698ca66d07a76ade0d5c46, which has appended a NULL entry as the final member of the pageflag_names[] array. Without the patch, a message that indicates "crash: failed to read pageflag_names entry" is displayed during session initialization in Linux 4.6 kernels.
