This indicates that part of the problem is that due to high a load too many of PPP's LCP packets were either dropped or queued up too long. As a work-around for that issue you might want to try installing luci-app-sqm and sqm-scripts and intantiate sqm on pppoe-wan with download/ingress bandwidth set to say 85% of the nominal download bandwidth and upload/egress set to 95% of the nominal upload bandwidth. That should leave enough slack for PPP's LCP packets to not be crowded out.
This will not help with the kernel warning (it might make triggering that less likely but it will not address the warnings root cause, AFAIKT).
