Same problem .... rasp pi 3 b

I have 40 brand new Cavium R270-T60-V6 systems (T32 BIOS) with CentOS 7.3.1611 installed. Five of them are failing at boot with:

    kdumpctl[9698]: Could not find a free area of memory of 0x10000

bytes... kdumpctl[9698]: locate_hole failed kdumpctl[9698]: kexec: failed to load kdump kernel kdumpctl[9698]: Starting kdump: [FAILED]

The systems are identical in every way (Memory, CPU, disks, firmware, network, location....).

A comparison of their "dmesg" output shows no smoking gun, but I do not know if differences like this are significant:

< efi: ESRT=0x13ffe1b0e98 SMBIOS 3.0=0xfffeb000 ACPI 2.0=0x13feaba0000

...

efi: ESRT=0x13ffe1b0e98 SMBIOS 3.0=0xfffeb000 ACPI 2.0=0x13feab9f000

< Memory: 533473024K/536820736K available (7232K kernel code, 1406K rwdata, 3456K rodata, 1152K init, 6589K bss, 2823424K reserved, 524288K cma-reserved)

Any tips on where to look next are appreciated.

(Also, if there is a more appropriate distro for this question, please advise).

Peace.
