No, I haven't opened a request. But my DSL crash reports have been sharing with them, I guess? Because I have Line Disconnect Reports and Product Improvement Program enabled.
On the first installation, BITSWAP, SRA, G.INP, G.VECTOR AND UPBO and all the VDSL profiles were enabled.
I could not see any entry for LCP in the system logs.
I am on 3.7.2 stable version.
