Description:
------------
using the container image php:8.0.10-fpm-bullseye, I deployed a simple php web server in my kubernetes cluster. The php-fpm process crashes with "Bus Error" at boot.

However I can fix this, by disabling hugepages from sysctl.conf. 

I need a way to use php-fpm under my kubernetes cluster without disabling hugepages.

kubernetes version: 1.21

containerd version: 1.4.9

OS: debian bullseye

kernel: 5.10.0-8-amd64

Test script:
---------------
Deploy any php-fpm container in any kubernetes cluster with hugepages enabled.

Expected result:
----------------
not a crash of php-fpm

Actual result:
--------------
a crash of php-fpm

Would you be able to provide a stack trace by any chance?

The bug report suggests that it is related to the use of transparent huge pages (THP) in the kernel. A possible workaround is to disable THP on the host machine by running:

echo never > /sys/kernel/mm/transparent_hugepage/enabled

Alternatively, you can try to use a different PHP container image that does not use bullseye as the base OS, such as php:8.0.10-fpm-buster or php:8.0.10-fpm-alpine.
