Ok. I'm glad there's an explanation eventually. > I will file a kernel bug report, and see if the kernel developers > can be convinced to map HIGHMEM with kmap() (as is apparently > necessary) for memtest. Please be kind enough to forward us the bug report URL once it's been filed: I'm obviously interested in tracking how far this goes. While we're at it, I would consider it only fair if that sentence, that can be found on the Liberté Linux homepage, was promptly fixed: "Liberté also correctly implements other features, such as wiping memory in order to prevent cold boot attacks, whereas Tails uses the simplistic sdmem, which erases at most 3 GiB of memory on a standard 32-bit kernel." (Yeah, I've seen the warning on top of the page, but still.)
