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.
