Generates unbootable initrd: Out of Memory Error

[殷啟聰 | Kai-Chung Yan]

I am currently using Cosmic (which is not released yet) and version 0.131ubuntu10 of "initramfs-tools" always generates unbootable initrd. After I select the kernel to boot during GRUB it says: "Loading initial ramdisk... Error: Out of memory". And then it halts forever.

This issue appears on all kernel versions.

The system is on UEFI + GPT.

Note that I don't have a swap partition on my system, but I don't think it's the cause.

This bug seems to be fixed in the latest release (0.131ubuntu15).

Hi Kai-Chuang Yan,

I have the same problem when I want to change the system's kernel version.

After compiling the Kernel 4.20, I update-grub and reboot. However, it says: "Loading initial ramdisk... Error: Out of memory".

What did you mean that this bug is fixed in the 0.131ubuntu15?

Thanks!

Add: this problem only happens in new kernel version. I can boot system with the old kernel version.

I mean the kernel is bootable is you install 0.131ubuntu15 and regenerate the initramfs. They have a later version now, hopefully it fixes the issues as well.
