From: Petr Tesarik <ptesarik@suse.com> Date: Thu Nov 5 11:51:49 2015 +0100 Subject: Add kernel initdata to boot requirements References: bsc#953732 Patch-mainline: v.0.8.16 Git-commit: 96c35d6d53115684003f26c5415e82404e39a6dd Kernel memory requirements at boot are greater than at run time. The values are based on SLE12 (or SLE11 for architectures missing in SLE12).
