File kdump-remove-root-and-resume.patch of Package kdump
From: Petr Tesarik <ptesarik@suse.cz> Date: Thu Sep 18 10:15:59 2014 +0200 Subject: Remove root= and resume= from the kdump kernel command line References: bnc#883883 Patch-mainline: v0.8.16 Git-commit: 8caaba657548133d476b2a13fd5abb68314927c7 Resume from hibernation should never be even attempted in kdump. If using dracut, the module is even omitted from the initrd, so passing the command line option only consumes command line space. The default root device is not needed either, because all required filesystems are handled by the mount dracut module. In fact, if the root filesystem is also mounted, it may be mounted twice.
