Linux - ARM - page allocation failure:

I received the following error:

ip: page allocation failure: order:10, mode:0x140c0c0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null)

I assume that the kernel wants to allocate 2^10 pages thats 4MB. There is no free contiguous 4MB memory chunk in "Normal" memory.

If that is true please tell me what can be done?

I have 2G memory, kernel 4.14.158:

Memory: 1994532K/2096124K available (10240K kernel code, 796K rwdata, 3220K rodata, 1024K init, 591K bss, 36056K reserved,
65536K cma-reserved, 1498108K highmem)
