please check patch in http://lkml.org/lkml/2010/11/13/181
BTW, you also need to ask your BIOS guys to fix the SRAT table. If you only have 128 cpu entries in MADT, SRAT table should have 128 cpu entries instead of 256 cpu entries otherwise, RHEL 5.5 could have problem. it will throw away last cpu entry in SRAT, (NR_CPUS is 255..., and last entry still could point the right cpu in MADT) Also BIOS should keep cpu entries in SRAT have same order to that in MADT.
Thanks
