Is this llvm or mesa issue ?
I also tried older kernel 4.16 same thing.

What reports do you need ?

Looks like sctx->bindless_descriptors->gpu_address is not accessable by gpu.
2e00000 is not in buffer list.

Well this is bug when using bindless textures and framebuffer which is also
resident in bindless textures.
There is no more fault if i comment out si_upload_bindless_descriptor function.

        radeon_emit(cs, PKT3(PKT3_WRITE_DATA, 2 + num_dwords, 0));
        radeon_emit(cs, S_370_DST_SEL(V_370_TC_L2) |
                    S_370_WR_CONFIRM(1) |
                    S_370_ENGINE_SEL(V_370_ME));
        radeon_emit(cs, va);
        radeon_emit(cs, va >> 32);
