You provided 1 error report, and here you list 3 CPUs.
Which CPU the error belong to? All of them?
It makes sens you get this on the arm1176jzf-s, because the ARMv6 arch
doesn't provide the VLDM/VSTMDB instructions.
Per the datasheet "ARM DDI 0301H ID012310":
ARM1176JZF-S processors support: PKHBT, PKHTB, QADD16, QADD8, QADDSUBX,
QSUB16, QSUB8, QSUBADDX, SADD16, SADD8, SADDSUBX, SEL, SHADD16, SHADD8,
SHADDSUBX, SHSUB16, SHSUB8, SHSUBADDX, SSAT, SSAT16, SSUB16, SSUB8,
SSUBADDX, SXTAB16, SXTB16, UADD16, UADD8, UADDSUBX, UHADD16, UHADD8,
UHADDSUBX, UHSUB16, UHSUB8, UHSUBADDX, UQADD16, UQADD8, UQADDSUBX,
UQSUB16, UQSUB8, UQSUBADDX, USAD8, USADA8, USAT, USAT16, USUB16, USUB8,
USUBADDX, UXTAB16, UXTB16
