x11 segfaults on Intel HD 5500

[Jaap Boender <jaapb%kerguelen.org@localhost>]

Hi list,

Since upgrading to NetBSD 8.0, X segfaults on Kaveri. It doesn't happen 
straight away (I can run X -configure without problems), but 
systematically when the window manager (twm or spectrwm are the ones 
I've tried) kicks in.

The problem goes away when setting DRI to false and NoAccel to true.

I used to be able to run modular-xorg on 7.1 without problems (apart 
from some redrawing that didn't get done - annoying but not 
debilitating), but on 8, both modular and standard X show the same problem.

I've got an Intel HD 5500 chip; dmesg and Xorg log (the latter for the 
working setup; X segfaults without leaving a log if the error occurs) 
are attached.

The backtrace:

Is this a bug or is there a problem with my setup somewhere? If I can 
help debug further (or if I should rather send this in as a bug report), 
please let me know.

best
