Sujata Kurup 2023-06-16 08:47:18 UTC Doc Text .Memory allocation for `kdump` fails on the 64-bit ARM architectures

On some 64-bit ARM based systems, the firmware uses the non- contiguous memory allocation method, which reserves memory randomly at different scattered locations. Consequently, due to unavailability of consecutive blocks of memory, the crash kernel cannot reserve memory space for `kdump`.

To work around this problem, you must install the kernel version provided by RHEL 8.8 and later. The latest versions of RHEL supports the `fallback` dump capture mechanism that helps to find a suitable memory region in the described scenario.
