Kernel

The following kernel related features and functionalities are deprecated in Oracle Linux 9.

crashkernel=auto Option

The crashkernel=auto option is deprecated and no longer supported on Oracle Linux 9 and is also unsupported for UEK R7. Some platforms, such as the Raspberry Pi have maximum limits for crashkernel memory reservation and these must be specified explicitly. This option will be removed in a future UEK release.

Asynchronous Transfer Mode

Asynchronous Transfer Mode (ATM) encapsulation enables Layer-2 (Point-to-Point Protocol, Ethernet) or Layer-3 (IP) connectivity for the ATM Adaptation Layer 5 (AAL-5). Currently, these protocols are used only in chipsets that use ADSL technology, which are being phased out.

kexec_load in kexec_tools

The kexec_load system call for kexec-tools is deprecated.

The kexec_file_load system call replaces kexec_load and is the default system call.
