Lots of bugs in 32-bit x86 Linux entry code

The really fun part was when they launched the first 64 bit Atom CPUs (Bay Trail) and then a bunch of them got shipped with only 32 bit UEFI and cannot boot in 64 bit mode.

They have to _boot_ with a 32-bit UEFI bootloader, but can run a 64-bit kernel and userland. Fedora Linux even allows for this while keeping secure boot on; Debian supports it as well but the interaction with secure boot is buggy, so you need to turn it off. Not sure about other distros, however.

Early 64-bit Intel Macs also shipped with a 32-bit UEFI limitation, but they were able to boot into a 64-bit system.
