Name
crashkernel — Reserve a portion of physical memory for kexec to use.
Synopsis
crashkernel=
n[KMG]@start[KMG]
The kexec subsystem likes to have a portion of physical memory
reserved for it. This option reserves that memory from the rest of
the kernel and will switch to use it if the kernel panics.
n specifies the amount of memory to
reserve, and start specifies the location
for this memory chunk. Both are measured in units of kilobytes
(K), megabytes (M), or gigabytes (G).
