Package: linux-image-5.2.0-3-amd64
Version: 5.2.17+1
Severity: important

Dear Maintainer,

Dear Maintainer,

OOM handling appears to be broken in 5.2.17-1 if hugepages are enabled.

Test system: AMD A4-5300, 40G RAM, no swap, booted disklessly.

Without hugepages enabled can compile dpdk without any issues. With huge
pages enabled it will reproducibly OOM when trying to link one of the
libraries. There are 20G+ free RAM at that point according to free with the
rest being mostly used as buffers.

It is sufficient to just enable huge pages to trigger this (2G out of 40G),
they are not allocated or used by anything.

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
