who is trying to load linux_kernel_bde if we are not running sonic service?
backlist does not prevent it from being loaded as a dependency for another kernel module that is not blacklisted, are there any other modules depending on this module that could still start this?

it is automatically loaded by kernel based on the pcie id. @jipanyang , user-bde and bnet bde are not pci driver, they will not be automatically loaded.
