The hang is caused by a reference in sched_clock() to the percpu data area before it is initialized. I know there was discussion about this late last summer & I thought Tony posted a patch. Does anyone recall the status. AFAICT, we see failures on SN systems but other IA64 systems work ok. --- Jack
