I tested this both with Linus rc4 and drm-intel-nightly from today (rc7).
In both cases I still experience a GPU hang with the single (apart from
noresume) kernel cmd line option intel_iommu=igfx_off.
For rc4, I saw a new error code, though:
Mar 10 14:27:46 hat kernel: [ 56.843611] [drm] GPU HANG: ecode
9:0:0x87f99ff9, in gnome-shell [1742], reason: Ring hung, action: reset
I attach the corresponding crash dump file.
This means that the only way, so far, to avoid hangs is i915.enable_rc6=0.
I have confirmed that this is also true for rc7 (drm-intel-nightly).
