Also to clarify, since vmalloc memory is biased to be allocated from highmem, in his 1GB/3GB kernel it comes from physical memory above his kernel's 3GB "unity-mappable" range. And his system happens to have a 1GB chunk of physical memory from 4GB to 5GB physical, so his vmalloc memory comes from the physical address 0x100000000 and above. Data is read OK on the live system from that region of memory, but when read from the same physical address on the dumpfile, it always returns zeroes. Dave
