On my Lenovo T430 and X230 X started crashing in February. It happens when I use mupdf of firefox. So to test install mupdf and open any pdf file.
It seems something changed in either xorg-server or some related GL library or perhaps in the i915kms module.
I have to beadm environments.
First one where X does not crash:
xorg-server-1.18.4_10,1 and mesa-dri-18.1.9_2
second one where X crashes:
xorg-server-1.18.4_11,1 and mesa-dri-18.3.2
The X230 has a Intel Core i7-3520M CPU @ 2.90GHz. The T430 has a Intel Core i5-3320M CPU @ 2.60GHz.
OS: FreeBSD 11.2-p9 or FreeBSD 12
I am adding an attachment with backtrace from X. I may be able to compile X or other ports with debug info if that helps.
The crash can be avoided by creating a xorg.conf configuration file in /etc/X11 with the following under Section "Device"
Option "AccelMethod" "sna"
It seems this also happens on some versions of Linux on the same hardware but I have not tested this.
I do not see the crash on my Intel NUC which has a Intel Core(TM) i5-4250U CPU @ 1.30GHz.
possible duplicate of bug #235487.
Is this still an issue, even with updated graphics drivers?
