Hi
Allthough there is still about one forth of memory available (7976kB
among 32MB), oom-killer is invoked and makes a victim.
What could be the reason and how could it be solved ?

I'm interested in your platform, though, with 512KB and 8MB hugepages. Could you send the .config and also describe the system a bit more?

I'm not sure I understand what you mean. The allocation is order 1, yes, does it explains why OOM killer is invoked ? > > I'm interested in your platform, though, with 512KB and 8MB hugepages. > Could you send the .config and also describe the system a bit more? How > many cpus are there and does this always happen? It is a home made board designed 15 years ago. There is only one CPU and there is 32 Mbytes of DRAM on the board. The processor is a MPC866 (powerpc 8xx family). Its MMU supports 4 page sizes (4k, 16k, 512k and 8M). Yes the problem always happens, it happens when the watchdogd get started, at the end of the startup, and there is always approx 8Mbytes available at that time. We are running a 4.9.x kernel, with commit 4b91428699477 from 4.10 backported on it.

Yes, show_migration_types. But I do not see why unmovable pageblocks should block the allocation. This is a GFP_KERNEL allocation request essentially - thus unmovable itself. This smells like a bug.
