the problem seems to me that memory allocation issue with higher
resolution monitor.
When issue happening, the grub shell not able to read some files
(depends on current memory usage).
For instance, I create 20M, 30M, 40M, 50M ... 80M, 90M, 100M, 101M, 102M
... 110M, 120M, 130M, etc... files and try to read them in grub shell.
The "ls -al" only list the part of files.
sometimes:
"20M, 30M, 40M, 50M ... 80M, 90M, 100M, 101M, 102M"
sometimes:
"20M, 30M, 40M, 50M ... 80M, 90M"
sometimes:
"20M, 30M, 40M, 50M ... 80M"
when force "ls -al test-130M", it will show "out-of-memory"
it looks to me that depends the current memory usage.
Based on my test, this issue is likely relate to EFI or grub (or
initramfs config) instead of kernel.
For the people be blocked by this issue, the best practice should change
the initramfs compression method to reduce the file size as what ybdjkfd
shared in comment#41.

Bug description:
Upgraded from 19.04 to current 19.10 using "do-release-upgrade -d".
Can still boot using the previous 5.0.0-25-generic kernel, but the
5.2.0-15-generic fails to start.
On selecting Ubuntu from Grub, the message "error: out of memory." is
immediately shown. Pressing a key attempts to start boot-up but fails
to mount root fs.
Machine is HP Spectre X360 with 8GB RAM. Under kernel 5.0.0, free
shows the following (run from Gnome terminal):
