# Kernel Version string for the -kdump kernel, such as 2.6.13-1544.FC5kdump # If no version is specified, then the init script will try to find a # kdump kernel with the same version number as the running kernel.

For example: # KDUMP_COMMANDLINE="ro root=LABEL=/" # Dracut depends on proper root= options, so please make sure that appropriate # root= options are copied from /proc/cmdline. In general it is best to append # command line options using "KDUMP_COMMANDLINE_APPEND=". # If a command line is not specified, the default will be taken from # /proc/cmdline KDUMP_COMMANDLINE="" # This variable lets us remove arguments from the current kdump commandline # as taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline # NOTE: some arguments such as crashkernel will always be removed KDUMP_COMMANDLINE_REMOVE="hugepages hugepagesz slub_debug quiet log_buf_len swiotlb cma hugetlb_cma ignition.firstboot" # This variable lets us append arguments to the current kdump commandline # after processed by KDUMP_COMMANDLINE_REMOVE KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off numa=off udev.children-max=2 panic=10 acpi_no_memhotplug transparent_hugepage=never nokaslr hest_disable novmcoredd cma=0 hugetlb_cma=0 pcie_ports=compat kfence.sample_interval=0 initramfs_options=size=90%" # Any additional kexec arguments required.
