Compress the kernel with kgzip(1). Make sure you have rescue media or a backout strategy (because the kernel won't boot). Reboot to kgzip(1)'d kernel. Die at the loader(8) BTX Halt (after the beastie menu, at the time the loaded kernel is executed). >Fix: Remove the bxe(4) driver from your custom kernel. kgzip(1) kernel now works. Not sure what is wrong with the layout of the bxe(4) driver, but it breaks the ability to utilize kgzip(1) -- which can reduce your monolithic custom kernels to about 1/3rd their original size (making them excellent for installer media).
