Yes, they are unrelated.
Issue 1: nf_conntrack: table full, dropping packet => Fixed with 4.2.4
Issue 2: Alignment trap: not handling instruction => Happens when ipset 
counters are enabled

Please keep in mind it happens with IPv6 commands.

Currently 4.2.4 without ipset counters runs well.

Ciao,
Gerhard
