            Bug ID: 15952
           Summary: Grub fails to load large rootfs files
           Product: buildroot
           Version: 2023.11.1
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: ian_ormshaw@waters.com
                CC: buildroot@uclibc.org
  Target Milestone: ---

Created attachment 9715
  --> https://bugs.busybox.net/attachment.cgi?id=9715&action=edit
Patch file

In some systems grub fails to load the rootfs.cpio as an initrd if it is too
large.

On the system I am currently testing a 61MB file load successfully while a
174MB file does not.  With the larger file grub outputs an out of memory error.
 The attached patch file allows the system to boot successfully.

--- Comment #1 from Yann E. MORIN <yann.morin.1998@free.fr> ---
Dr I J Ormshaw, All,

This is a grub limitation, so please work with grub upstream to lift that
limitation. Once they have accepted a fix, then we can see whether we can
backport it or not.

Regards,
Yann E. MORIN.
