Does running clinfo on the command line work?
Can you try running gdb ./blender --debug-cycles from the command line, then when it hangs, press ctrl + c and type bt? Then attach the terminal output here.
Are you using the Latest Release or a Pre-release of those Intel OpenCL drivers? It may not be a bug in Blender, since there's not a lot we do besides querying some information about OpenCL devices at that point.

You are using an old version of 2.8 (from the 13th of April). Would suggest to try with the latest

New test done with latest build (d2f1705b15)

clinfo output:
clinfo.txt

Running just ./blender on latest beta, freeze is still there, needing a killall blender.

I was not able to run the debugger with the command gdb ./blender --debug-cycles, but I was able to just start gdb then file ./blender, set args --debug-cycles, then run.
That entire command sequence, and output.
gdb.txt

The OpenCL drivers are a release for Ubuntu >16.04, kernel >4.11. I did my tests on Ubuntu Studio 18.10, with kernel version 5.0.9 (built from source), and the default kernels for U.Studio 18.10 (4.18.0-17-lowlatency, 4.18.10-17).

Could this be closed since it's from the past month?

In the latest build, this seems to be fixed. It no longer freezes.
