--- Comment #13 from Alex Deucher <alexdeucher at gmail.com> --- Can you revert parts of the patch to find out which element is causing the problem. E.g., try: /* reset data block */ // ctx->data_block = 0; and see if that helps, then: /* reset divmul */ // ctx->divmul[0] = 0; ctx->divmul[1] = 0; etc. Additionally, can you dump the display registers in the working and non-working states using radeonreg (http://cgit.freedesktop.org/~airlied/radeontool/)? (as root) boot with broken kernel: ./radeonreg regs dce3 > broken.regs boot with working kernel: ./radeonreg regs dce3 > working.regs -- You are receiving this mail because: You are watching the assignee of the bug.
