Can you send me the output of cpuid-etallen?  It's pretty long, so
maybe off list would be better...  It's from a port of the same
name...

Also, it looks like a microcode update could fix this issue, have you
tried to look at that?

Looks very similar to your issue, though it's a different microarch..
Your's is a Haswell that has the TSX bug in it, and it could be that
the bios is disabling too many feature bits...

Have you made sure that your machine has the latest BIOS?  A newer
BIOS could reenable the feature too...

There should be an AESNI feature on this line, but clearly not...

Which is why you get this...
