what mainline kernels crash and how will they crash? Fedora and other
distros have had 4K stacks enabled for years:

$ grep 4K /boot/config-2.6.24-9.fc9

and we've conducted tens of thousands of bootup tests with all sorts of
drivers and kernel options enabled and have yet to see a single crash
due to 4K stacks. So basically the kernel default just follows the
common distro default now. (distros and users can still disable it)
