AcidSlide: I just noticed this after reviewing the logread, it seems the issue is related to dnsmasq and dhcp Most of the mtk_soc_eth error happens just a few seconds after a dnsmasq read

AcidSlide: Downgrading to 19.07.3 to see if issue exists |
|
AcidSlide: I would recommend this as a regression bug, since i went back to 19.07.3 no issues encountered with mtk_soc_eth. I'll be monitoring it for the next 24hrs. [UPDATE] |
