Public bug reported: Every night I suspend my laptop and resume it in the morning. At least once a week, the X server crashes with SIGBUS when resuming from suspend.
I scoured systemd journals and all logs under /var/log, and this was the only suspicious message I found: [ 59358.134] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied As my graphics card uses driver i915, I installed xserver-xorg-video- intel-dbg but couldn't find any package with debugging symbols for xserver-xorg-core, so running 'sudo gdb --core=/core' only yielded this: Core was generated by `/usr/lib/xorg/Xorg -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -noliste'.
