Bug in latest kernel 3.16.7-13 security patch

Hi,

There is a bug <https://bugzilla.opensuse.org/show_bug.cgi?id=927018>
in the latest kernel security patch which prevents a graphical login
if you are running nVidia graphics with the proprietary drivers. I'm
not sure if it applies to other graphics cards.

They are working on a fix, but for now I am staying with kernel
3.16.7-7 and not upgrading to 3.16.7-13.

Good luck,

Bob

Not quite. It prevents reusing nvidia modules that were compiled for
earlier kernel releases in 13.2. Just rebuild (or reinstall) drivers
under new kernel. Of course as new kernel version with fixes will
hopefully be released soon, it makes sense to wait, otherwise modules
built under -13 will be incompatible with next update again :)

It will apply to any kernel module.

Thanks for the clarification, Andrei. I hope the fixed kernel versions
will be 'announced'?

I have retracted the old kernel update. We will be publishing a fixed
in the next days / early next week.

Ciao, Marcus
