The kdump initramfs has included NIC device drivers such as ice, iavf, i40e, mlx5* and the like. Loading these drivers in a kdump environment is problematic, because these drivers are known to consume a lot of memory. In addition, the systemd-sysctl.service systemd unit causes the following sysctl to be set, which forces the kernel to keep more than 1 GiB of free memory, which results in out-of-memory conditions: "vm.min_free_kbytes=1179648". All of these introduce a possibility of not being able to collect a vmcore file after a kernel crash. There is a need to exclude unnecessary NIC drivers from the kdump environment and prevent the sysctl settings from taking place to make vmcore collection more reliable. Verification: - build-pkgs; build-iso; install and boot up on aio-sx lab. - All these backlist drivers are not loaded in kdump kernel. Closes-Bug: 2038804 Signed-off-by: M.
