On system startup I receive this error:
==482202==
vex amd64->IR: unhandled instruction bytes: 0x62 0xF1 0x7F 0x48 0x7F 0x84 0x24
0x30 0x0 0x0

==482202== valgrind: Unrecognised instruction at address 0x402f1b8.
==482202== at 0x402F1B8: _dl_start (in /usr/lib64/ld-linux-x86-64.so.2)
This translates to (objdump -d):
201b8: 62 f1 7f 48 7f 84 24 vmovdqu8 %zmm0,0x30(%rsp)
201bf: 30 00 00 00
which is part of the AVX512 instruction family (Move Unaligned Packed Integer
Values).
