Hi,

I just found that if I disable "AES NI" in BIOS setting, FreeBSD would
be able to detect it on boot with:

Features2=0x29ee3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,<b17>,DCA,SSE4.1,SSE4.2,POPCNT,AESNI>

However if it's set to "enabled" I got:

Features2=0x9ee3fd<SSE3,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,<b17>,DCA,SSE4.1,SSE4.2,POPCNT>

The CPU was Xeon L5630 and motherboard is Supermicro X8STi with BIOS
1.00c.  Should I consider this a BIOS issue with known workaround that I
consider "Disable" as "Enabled"? :)

Cheers,
