Comment 4 for bug 1553687

Hi,
the answer is no, it doesn't prevent the system from booting. Both if I press and if I don't press any key - system continue to boot up, but showing some other error messages before the background appears when it asks me for username and password.
I didn't have this error when I installed Xenial first time at the beginning of February, it appeared later after some updates (I'm not sure 100% but I think after kernel updates).
