  We address the question of whether thermal QCD at high temperature is chaotic
from the ${\cal M}$ theory dual of QCD-like theories at intermediate coupling
as constructed in arXiv: 2004.07259. The equations of motion of the
gauge-invariant combination $Z_s(r)$ of scalar metric perturbations is shown to
possess an irregular singular point at the horizon radius $r_h$. Very
interestingly, at a specific value of the imaginary frequency and momentum used
to read off the analogs of the ''Lyapunov exponent'' $\lambda_L$ and
''butterfly velocity'' $v_b$ not only does $r_h$ become a regular singular
point, but truncating the incoming mode solution of $Z_s(r)$ as a power series
around $r_h$, yields a ''missing pole'', i.e., $C_{n, n+1}=0,\ {\rm det}\
M^{(n)}=0, n\in\mathbb{Z}^+$ is satisfied for a single $n\geq3$ depending on
the values of the string coupling $g_s$, number of (fractional) $D3$ branes
$(M)N$ and flavor $D7$-branes $N_f$ in the parent type IIB set
(arXiv:hep-th/0902.1540), e.g., for the QCD(EW-scale)-inspired $N=100, M=N_f=3,
g_s=0.1$, one finds a missing pole at $n=3$. For integral $n>3$, truncating
$Z_s(r)$ at ${\cal O}((r-r_h)^n)$, yields $C_{n, n+1}=0$ at order $n,\ \forall
n\geq3$. Incredibly, (assuming preservation of isotropy in $\mathbb{R}^3$ even
with the inclusion of higher derivative corrections) the aforementioned
gauge-invariant combination of scalar metric perturbations receives no ${\cal
O}(R^4)$ corrections. Hence, (the aforementioned analogs of) $\lambda_L, v_b$
are unrenormalized up to ${\cal O}(R^4)$ in ${\cal M}$ theory.
