or, updated version:

\subsection{pw.x crashes in parallel execution with an obscure message
   related to MPI errors}
Random crashes due to MPI errors have often been reported, typically
in Linux PC clusters. We cannot rule out the possibility that bugs in
\qe\ cause such behavior, but we are quite confident that
the most likely explanation is a hardware problem (defective RAM
for instance) or a software bug (in MPI libraries, compiler, operating
system)
