I have no mystery crash on my test-systems. by the looks of it, your crashes seem to be pagetable related. If it's in the tip/xen-64bit branch, my candidates would be: 0f38c08: x86: use __page_aligned_data/bss 0337869: x86_64: there's no need to preallocate level1_fixmap_pgt 89d7bb5: x86_64: add workaround for no %gs-based percpu 0337869 is reverted already. Or if it's an older commit, two candidates would be: b50efd2: x86: introduce page_size_mask for 64bit 3a9e189: x86: map UV chipset space - pagetable do you know the sha1 of the first broken tree? We know that tip-history-2008-07-08_16.08_Tue is known-good.
