I just had a similar error message on boot:

init: ureadahead-other main process (531) terminated with status 4
udevd [513]: can not read '/etc/udev/rules.d/z80_user.rules'

It stopped the booting process.

After a reboot it didn't happen again and everything went normally.

Same here

udevd[397]: can not read '/etc/udev/rules.d/z80_user.rules'

anyone got a fix?

[KIAaze]

I just removed the file.
It doesn't belong to any package according to dpkg -S, the ubuntu package site or apt-file search (suspect!).
And if I remember correctly, it was even an empty file.

You can move the file to a safe location for backup if you want.

Also, I recommend reading man udev to understand what such files are supposed to do and what their names and permissions should be to work:

man udev

anyone got a fix?

gksudo /etc/udev/user.rules

Add in a single "#" to the previously empty file, save and close the file. No more errors.

gksudo /etc/udev/user.rules

Add in a single "#" to the previously empty file, save and close the file. No more errors.

That works for me! But can you please explain the reasons to why that worked/why the error was happening?

The error is probably happening because they're checking if the file exists and has non-zero size. The file exists, but it has zero size, so the check was failing. But it would just carry on. Putting a comment in there lets it think the file exists, and when it reads the file, it still gets nothing as was the case before.
