@Peter Wu: ok, got it. Sorry for any inconvenience (for subscribing hybrid-graphic-linux to this bug). By the way: thanks for the tip. I decided to test some different kernels and see how they behave with amdgpu.
Some 4.4.X and 4.5.X kernels didn't work either, but I'm currently testing kernel 4.6.0-040600rc7-generic (version "v4.6-rc7-wily") with the module amdgpu loaded along with modules amd_iommu_v2, amdkfd, drm, drm_kms_helper, i915, ttm, video etc. and so far my laptop hasn't stopped (hang/freeze) not even once! It's been ~5 hours of testing, so far, and I already performed a lot of tasks that usually cause the lockups (previewing OpenGL screensavers on Xscreensaver, running 3D games, 3D CAD applications et cetera: all these would cause a CPU hard lockup or kernel panic) but I didn't experience any issue with kernel v4.6-rc7-wily. I will also test kernel 4.7 as you suggested.
