I have read the contributing guide lines at https://github.com/opnsense/core/blob/master/CONTRIBUTING.md
I am convinced that my issue is new after having checked both open and closed issues at https://github.com/opnsense/core/issues?q=is%3Aissue

Describe the bug Since upgrading to an Intel N100 SoC (Asrock N100M) the system crashes daily. Probably related to the following pfSense bug: https://redmine.pfsense.org/issues/14648 Workaround: https://redmine.pfsense.org/projects/pfsense/repository/2/revisions/aed18fb07d387c90942b729c02fe460064310f5e/diff/src/usr/local/www/includes/functions.inc.php

To Reproduce

Run OPNsense on new Intel NXXX SoC

Expected behavior

No crashes

Describe alternatives you considered

Currently testing the following changes in system.inc:103-108

$totalMem = (int) get_single_sysctl("vm.stats.vm.v_page_count");
$inactiveMem = (int) get_single_sysctl("vm.stats.vm.v_inactive_count");
$cachedMem = (int) get_single_sysctl("vm.stats.vm.v_cache_count");
$freeMem = (int) get_single_sysctl("vm.stats.vm.v_free_count");
$result['memory']['total'] = (int) get_single_sysctl('hw.physmem');

I’m beginning to suspect these N100/Adler Lake things are broken by design and can only be fixed by microcode updates as discussed here https://forum.opnsense.org/index.php?topic=37055.0 (German thread) and that this in particular is just one of the friendlier side effects.

I doubt empty($value) is a good choice here as it will transform 0 to ''. The caller knows best what value is expected. Certainly for arithmetics the caller should make sure it is dealing with integer (or possibly float) values.

But I also think the kernel or harware is glitching here if it returns 0 on memory. 😉
