This might be related to the link loss: https://forum.openwrt.org/viewtopic.php?id=63225

Additional info: The bootloader is U-Boot, but a roughly 12 month old version from LEDE trunk:
U-Boot 2013.10-openwrt4 (Feb 16 2017 - 12:32:56) VGV7510KW22
Board: Arcadyan VGV7510KW22
SoC: Lantiq VRX288 v1.2
hailfinger:
Device: VGV7510KW22 / o2 Box 6431
Software version: OpenWrt SNAPSHOT r5944-ad4232e Linux version 4.9.77 (buildbot@slashdirt-03) (gcc version 5.5.0 (OpenWrt GCC 5.5.0 r5944-ad4232e) ) #0 SMP Thu Jan 25 10:00:48 2018
Environment: Additional packages: asterisk13-chan-lantiq, strongswan
Steps to reproduce: From time to time, the box will reboot spuriously. Uptimes vary, between 12 hours and 2 weeks. After such a reboot, some of the ethernet ports do not detect a link anymore. Unplugging and replugging the ethernet cable into the same port does not help, and the kernel will only notice a link if I plug the ethernet cable into another port. Sometimes, the ethernet port loses link even without a reboot. Syslog is logged to an external server via UDP and does not show any error message prior to the spurious reboot.
Workaround: Performing a manual reboot after the spurious reboot fixes the ethernet link loss.
Possibly relevant difference between dmesg on a spurious and normal reboot:
