# \[PATCH 2/2\] fadump: Disable deferred page struct initialisation - From: Srikar Dronamraju \ - Date: 2016-08-02 13:19:48 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2016/08/6481591 - Thread: https://ratatoskr.run/linux-mm/2016/08/6481589/t.md ```text Fadump kernel reserves significant number of memory blocks. On a multi-node machine, with CONFIG_DEFFERRED_STRUCT_PAGE support, fadump kernel fails to boot. Fix this by disabling deferred page struct initialisation.
