any limitation about size of
/initrd.img that saved by populate_rootfs ?

i got

RAMDISK: Compressed image found at block 0
RAMDISK: incomplete write (-28 != 2048) 134217728
crc error
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 388k freed
init_special_inode: bogus i_mode (177777)
Warning: unable to open an initial console.
init_special_inode: bogus i_mode (177777)
init_special_inode: bogus i_mode (177777)
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

before that
checking if image is initramfs... it isn't (no cpio magic); looks like an initrd
Freeing initrd memory: 25735k freed.

that only happen one system (64G RAM) and SLUB.

if using SLAB, it works well.

somewhere the ramdisk or /initrd.img get corrupted..
