Re: [Xen-devel] Crash on boot with 2.6.37-rc8-git3

I think my math is off here. The reserve call is made on the

What happens if you fudge the code so it allocates those pages to be
page aligned. So df65a000->df66e000 ? We skip this way the region
df659800->df659fff and start on a new PFN (and pte).

I get (though the photo isn't clear in places) df659000->df66cfff and it crashes at find_range_array+0x4d/0x56 which traces back to the call of memblock_find_dma_reserve from setup_arch in arch/x86/kernel/setup.c . So it still crashes, but at a slightly later stage.
