Hello, Found that there is a BDW GPU hang bug with iommu enabled in free desktop Bugzilla since two years ago, and it is still not closed: https://bugs.freedesktop.org/show_bug.cgi?id=89360 The last duplicated issue is 99964 which was reproduced with linux-4.10. Does anyone know if linux-4.11 and the later versions have this issue fixed or not? Thanks Chuanxiao _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
