clinfo gets hanged


Just installed amdgpu-pro-20.45-1188099-ubuntu-20.04 on a fresh Ubuntu 20.04.2 LTS install, with a MSI AMD RADEON RX 5700 XT connected, using this options:

./amdgpu-pro-install --opencl=legacy,pal --no-32 -y

When I execute /opt/amdgpu-pro/bin/clinfo it simply hangs

Stracing shows it hangs accesing kernel module:

ioctl(6, AMDKFD_IOC_MAP_MEMORY_TO_GPU, 0x7fffa1b5ed90) = 0

And never returns to shell until pressing Ctrl+C.

I also tryied updating amdgpu firmware with latest available:


 But it doesn't help.

I collected some logs for debugging this issue. Please help with this is appreciated. Tnx!
