running into OOM killer with kexec loading large ramdisk

[Tobias Powalowski]

Hi,
again me,
I try to load a 900MB ramdisk on a ramfs rootfs  with kexec and a 10MB kernel.
With 2800MB RAM assigned to qemu.
Memory free by /proc/memstat: 2.2GB
It keeps on OOM killed while executing:
kexec -l kernel --initrd=initrd.img
I can safely unpack the initrd in the ramfs without getting OOM killed.
What is kexec doing wrong here?
greetings
