With the logic pud error i found and that seems currently will stay for the forseeable future in the tree I don't think x86-64 64bit hotadds for more than 1GB have ever worked with the sparsemem method. Older trees (before 2.6.24) had also a different method that did preallocate everything based on the SRAT. That one should have worked for this case. -Andi -- 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/
