I've seen tests hang. I was working just now on a set of test results with a hang at 32 procs. It didn't hang at 2, 4, 8 or 16 procs -- only at 32. The test was:
export TESTsander='../../bin/pmemd.amoeba.MPI'; cd amoeba_wat1 && ./Run.amoeba_wat1.pmemd
I'm restarting that set of runs (32 procs) again to see if it is reproducible.
This is also rhel: gnu 4.4.6, RHEL Server 6.1, serial, 2012-03-22
...but I saw hangs on Ubuntu, too, yesterday.

Subject: Re: [AMBER-Developers] Amber12 release candidate 2: rism hang
Hi,
Red Hat 6.1, Intel 12.1.0, No MKL, x86_64, Only AmberTools serial 3/22/12 SRB
Configure command: ./configure intel
486 file comparisons passed
0 file comparisons failed
0 tests experienced errors
This test hangs:
if [ -n "testrism" ]; then cd ./rism1d/spc-kh && ./Run.spc; fi
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

No other tester reports a hang; there are some differences
between other intel 12 platforms: mostly ubuntu vs redhat, or
minor version numbers of intel 12.
Also other wiki reports do not mention whether MKL was used,
so it probably was; mine did not.
Intel 11 and 12 support the compiler flag -mkl, so
on this new machine that is the expected approach to getting MKL.
There are 1444 warnings produced during compilation.
These mention rism:
14862:rism_util.F90(603): warning #6843: A dummy argument with an explicit INTENT(OUT) declaration is not given an explicit value. [O_VARCOEF]
15151:rism1d_c.F90(1250): warning #6843: A dummy argument with an explicit INTENT(OUT) declaration is not given an explicit value. [START]
15154:rism1d_c.F90(942): warning #6843: A dummy argument with an explicit INTENT(OUT) declaration is not given an explicit value. [START]
