Please cc: me with any responses if at all possible. I'll attempt to follow the suggest format from http://kernel.org/pub/linux/docs/lkml/reporting-bugs.html. [1.] 2.6.30 and later kernel no longer boots using encrypted root filesystem setup [2.] Neither the 2.6.30 and 2.6.30.1 kernels will boot under my encrypted root filesystem setup on an x86 box, though the 2.6.29.x kernels still boot fine and the newer kernels boot fine if I do not use the encrypted filesystem setup. When I attempt to boot the 2.6.30.x kernels (via grub), the boot fails immediately, apparently in decompressing the kernel, giving the message "Destination address too large", which from grepping the kernel source tree, apparently comes from arch/x86/boot/compressed/misc.c My encrypted filesystem works by first booting from a very small (ca 30 MB), unencrypted, ext2 partition on sda1. This partition is passed to the kernel as the root partition by grub. This small partition contains only the kernel image plus a few binaries needed to run an init script that mounts the encrypted partition (sda2) via losetup and dmsetup, then pivots_root to it. However, since the 2.6.30.x kernels apparently never even decompress themselves, the process never gets this far. I can boot the same kernel successfully on the same machine by booting it from another, larger partition (sda4) which, if relevant, is an ext3 partition. I can also still boot the original encrypted system by using the 2.6.29.4 kernel with the exact same parameters and configuration as the 2.6.30.x kernels that fail. The only differences I see that seem relevant so early in the boot process is that the initial root filesystem (on sda1) for the encrypted boot setup is ext2 instead of the ext3 on the larger partition that boots successfully and that the size of the sda1 partition is much, much smaller.
