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.

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.

Looks like one of the assert bounds was wrong,

should fix this. Please confirm whether it fixes the issue for you.

Confirmed, that fixes it for me.
