@vt-alt would you be able to run cpuid -1 -r and send us the resulting data?

Ok so Brand String is stored in

   0x80000002 0x00: eax=0x65746e49 ebx=0x2952286c ecx=0x726f4320 edx=0x4d542865

   0x80000004 0x00: eax=0x382e3220 ebx=0x7a484730 ecx=0x00000000 edx=0x00000000

Because Little Endian we have to swap integers in each register which gives the following hex sequence

496e7465 6c285229 20436f72 6528544d 29206939 2d313039 30302043 50552040 20322e38 3047487a 00000000 00000000

0x06 is clearly not ending this sequence so this is a bug for sure.
Let me dig into this.
