FS#2384 - Asus WL500GP V2 crash

Supply the following if possible:
- Device problem occurs on - Asus WL500GP V2;
- Software versions of OpenWrt/LEDE - OpenWrt 18.06.4, r7808-ef686b7292
- Steps to reproduce - I’m not sure, just a higher load and utilizing the wireless connection. For example I’m loading the LuCi realtime graphs in the browser and start downloading a file from the local network.

I’m attaching a crashlog obtained via `cat /sys/kernel/debug/crashlog`. There seems to be a hint for the problem:

Is this a regression? I mean, 18.06.2 was working fine on this device and the problem happens only with upgrade to 18.06.4? Please also try to reproduce this problem with the latest snapshot image http://downloads.openwrt.org/snapshots/targets/brcm47xx/legacy/ and provide the crashlog again

I can confirm. Crash on higher load. WL-500GP v1 is also affected. I can reproduce it with some speedtest.net tests. pppoe + ethernet connection at LAN side. 18.06.4 and snapshot are also affected.
