Get that error logged on Trusty i386 with the latest 3.12.0.1 kernel on that fresh installation:
[ 1.024928] libahci: module verification failed: signature and/or required key missing - tainting kernel
As its a fresh installation, neither intel-microcode nor iucode-tool are installed.
Question: could it be also related to that other report ?
