I noticed the game becoming unresponsive for a few seconds while playing; I saw this in my kernel messages later:

[240918.898139] [drm] stuck on render ring
[240918.898845] [drm] GPU HANG: ecode 7:0:0x85dffff8, in lotroclient.exe [13281], reason: Ring hung, action: reset
[240918.898846] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[240918.898846] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[240918.898847] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[240918.898847] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

[240918.900045] drm/i915: Resetting chip after gpu hang

This is on an i5 4690k (HD graphics 4600) running with intel_iommu=on.

I'm not sure how reproducible this is.

From dump, we can note that we have in render ring :
  FAULT_REG: 0x000000c7
    Valid
    Invalid and Unloaded PD Fault (PPGTT)
    Address 0x00000000
    Source ID 24

and also in this log:
ERROR: 0x00000105
    TLB page fault error (GTT entry not valid)
    Invalid page directory entry error
    Cacheline containing a PD was marked as invalid

There were improvements pushed in kernel and Mesa that will benefit to your system, so please re-test with latest kernel & Mesa to see if this issue is still occurring.

Timeout. Assuming that it is fixed by now. If this is not the case, please re-test with latest kernel & Mesa (12-13) to see if this issue is still occurring since there were improvements pushed in kernel and Mesa that will benefit to your system.
