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

What reports do you need ?

another gallium dump

another dump, tried with propriery nvidia drivers. it works fine there.
Comment 7 Domen 2018-11-25 14:13:55 UTC
Looks like sctx->bindless_descriptors->gpu_address is not accessable by gpu.
2e00000 is not in buffer list.

0000014d
02e00000         SPI_SHADER_USER_DATA_COMMON_1 <- 0x02e00000

Comment 8 Domen 2018-11-27 07:58:37 UTC
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);
