This looks like [1] was reached with dir being NULL, though since you don't
have debugging symbols (and I don't know/can't seem to work out what address
intel_drv.so was loaded at) I can't know for sure. Having said that, this is
the only place where the result of readdir is not checked for NULL, so I don't
know how else this would happen. This bug was introduced by [2]. Can you please
try the attached patch? Whether or not this is the problem, I'll forward it
upstream.

James

Hi all,
I recently upgraded my xserver-xorg-video-intel package to the newest
jessie-backports (version 2:2.99.917+git20161105-1~bpo8+1). After a reboot, X
doesn't start anymore. I used this package from backports for several months,
so the newest update must have caused the trouble, I think.
After a downgrade to jessie stable (version 2:2.21.15-2+b2) X is starting fine
again, but I have no HW acceleration... :(
Please find attached the Xorg.log.
Just for information: I'm using Linux Mint Debian Edition, so my desktop is
Cinnamon. And I compiled my own kernel (which was no problem in the past). I
also tried some of my older kernels of the 4.8.x kernel series - just to be
sure that the problem is not introduced by the newest kernel upgrade.
Best regards,
Micha
PS: Please keep me in the loop when discussing this error as I didn't subscribe
to the backports mailing-list. Thanks!
