Backtrace

Running any Vulkan program which creates pipelines (vulkaninfo works, crash
info from vkcube) triggers an assertion:

../src/amd/vulkan/radv_cs.h:45: radeon_set_config_reg_seq: Assertion `reg >=
SI_CONTEXT_REG_OFFSET && reg < SI_CONFIG_REG_END' failed.

    radv: add more assertions to make sure packets are correctly emitted

No errors in dmesg

Commenting out the assert allows it to proceed and seems to work but I doubt
it's the right thing.

This should probably be a release blocker.
