Is this related to me seeing
[ 2.111424] mvneta: module verification failed: signature and/or required key missing - tainting kernel [ 2.126061] scsi_mod: no symbol version for _clear_bit [ 2.131257] scsi_mod: Unknown symbol _clear_bit (err -22) [ 2.138093] mvneta: no symbol version for _clear_bit [ 2.143117] mvneta: Unknown symbol _clear_bit (err -22) [ 2.144135] mvmdio: no symbol version for __gnu_mcount_nc [ 2.144138] mvmdio: Unknown symbol __gnu_mcount_nc (err -22) ...
