Kernel Fails to Boot after enabling " "zoned block device support" post compilation and installation.

Hello,
Request your help in understanding the issue here.
Used RHEL 8.2 and build the same kernel after enabling "zoned block device support".

Here are the steps :
1. took the source : kernel-4.18.0-193.el8.src.rpm
2. built the dev environment.
3. copy the .config fie from the running kernel : enabled "zoned block device support" and "drive-managed zoned block device target support",
4. compile the kernel, and install.

make -j 40
make module_install
make install.

It installs successfully. But fails to boot.
Attached the image of the failure.

Note : I tried with 5.x kernel (5.6), it works fine.
