--- Comment #3 from Timothy Arceri <t_arceri@yahoo.com.au> ---
If you build radeonsi with debug sysmbols i.e. use --enable-debug you should be
able to run gimp in gdb and see exactly were the segfault is. Could be as
simple as a NULL check missing somewhere.

Gimp does not segfault, it just freeze:

The same freeze occurs even on mesa master (19.1.0) from today.


This is the stack trace (with a Ctrl+C on clinfo frozen)

As previously said, commenting si_clear_buffer makes clinfo and opencl work
again (with mesa master from git)

This looks like a duplicate of 108879. I'm going to close this one as 108879 is
more generic.
KABINI si afaik CIK class GPU. Unfortunately I can't investigate as I don't
have any CIK hw.
