It broke the autofs feature of systemd (32bit) on a 64bit kernel, which
resulted in an endless wait in the boot process. I don't use the autofs
tools. I guess the fix in the autofs package to compensate the kernel
bug, which has now been fixed, breaks the autofs package.
The fix in the kernel makes systemd work correctly.
