Sorry for this false alarm. We found the root cause was due to a problem
in our testing environment, and it has been fixed now.

Hi Sai,
We encountered an "Initramfs unpacking failed" issue when doing boot
test on this patch. The patch is for printing accurate debug info under
compiler optimization, looks totally unrelated with initramfs, but this
issue is 100% reproducible in our tests. We confirmed that our rootfs
image, kernel config and other environments were consistent during the
testing. Could you please help check if this is a real problem or a
false alarm? Thanks.
Greeting,
FYI, we noticed Initramfs_unpacking_failed due to commit (built with gcc-11):
