--- Comment #32 from Sedat Dilek <sedat.di...@gmail.com> 2010-10-10 13:40:58 --- (Patch see https://bugzilla.kernel.org/show_bug.cgi?id=16140#c26) With applying my patch from above, it's this section (Line #1028 and following) from r100_cp_init() doing the problem: 940 int r100_cp_init(struct radeon_device *rdev, unsigned ring_size) ... 1026 radeon_ring_start(rdev); 1027 r = radeon_ring_test(rdev); 1028 if (r) { 1029 DRM_ERROR("radeon: cp isn't working (%d).\n", r); 1030 return r; 1031 } 1032 rdev->cp.ready = true; 1033 return 0; 1034 } ... Replacing "if (r) {" with "if (WARN_ON(r)) {" shows the above Call-trace. I looked into r600.c source-code and put "rdev->cp.ready = true;" before Line "r = radeon_ring_test(rdev);", not helping. Again inspired from r600.c, I put Line #966 "r100_cp_load_microcode(rdev);" after "r = radeon_ring_init(rdev, ring_size);", this resulted in a not-so-garbled screen, after hanging: pm-resume in X -> switching to vt-1 -> killing X -> restarting startx This is doing no harm, see my logs. - DRM_ERROR("radeon: ring test failed (sracth(0x%04X)=0x%08X)\n", + DRM_ERROR("radeon: ring test failed (scratch(0x%04X)=0x%08X)\n", I am not sure what you mean with "radeon driver": the one in the kernel or the DDX (xf86-video-ati). One NOTE: In Line #3728 there is a commented "r100_gpu_init(rdev);", it is nowhere "defined". I see in r600.c a *_gpu_init() and a *_cp_start() in case of resuming. Just a hint, if you wanna compare or dig into it. IIRC it would make sense to interprete correctly the Call-trace, I am not that familiar with "the internals". Sorry, I don't wanna experiment with older Linux-Kernels as my graphics driver stack is mostly latest-stable or from GIT, not sure what will happen.
