Kernel 4.2.3-200 stability problems and mouse cursor defects...

Fedora Devel,

Just wanted to get more information on a bug that bit me over the weekend.
Running Fedora 22 and updated to 'kernel.x86_64 4.2.3-200.fc22'.  There's
no mouse cursor on the login screen at all.  When logging in either on X11
or the Wayland session I repeatedly get Kernel Oops messages and the mouse
cursors jumps about and appears jittery or to make duplicated copies of
itself on screen.  Using Fedora is very difficult and things don't appear
stable or normal I get a message like this in the backtrace:

This appears similar to bugs:

Do you have further information on this?

Also I am unable to log-in to Buzilla to further report this problem and
have sent several reset password requests but no reset link has been sent
to me.

Thank you!
