panic: Canonical hash not found

[ligi]

Now that I was just mentioning the rinkeby node being so stable in (#15340) - also the Rinkeby node crashed:

Happens with version 1.7.2

These are the parameters I started it with:

geth --datadir=$HOME/.rinkeby --cache=1024 --syncmode=full --ethstats='WALLETH FCM push node:Respect my [email protected]' --rinkeby -rpc --rpcaddr 127.0.0.1 --rpcport 9003 --lightserv 23

Before this node was running for really long times with no crash at all. But I just recently added the "--lightserv 23' flag as I have the feeling to few Rinkeby nodes serve light-clients. And the trace indicates it might be a problem originating in this added flag.

Yes, I've told @zsfelfoldi about this exact problem. He said it's solved in the LES/2 PR.
