We test here SLES9 but with mvapich1 library 0.9.7 version from OFED.
We tried to run here the test you attached on mvapich1 but have not seen
Can you try to reproduce with mvapich1 version?
If not please send us detailed instructions how to reproduce with
mvapich2 (where to take sources, compile, etc.)
BTW when searching the SLES9 sources for the: Kernel BUG at page_alloc:853
We couldn't find it.
Which kernel version are you using? We use here 2.6.5-7.244-smp.
