With this patch, early boot would use pages from lower PFNs. Without the patch, it would use memory from higher PFNs. That is the only real difference. 1. Is there any chance that all of your memory is not being properly initialised? 2. Any chance of seeing a dmesg log? 3. If you boot with the patch reverted and then do something to consume all memory like build loads of kernel trees simultaneously, do you see any problems? -- Mel Gorman Part-time Phd Student Linux Technology Center University of Limerick IBM Dublin Software Lab -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
