--- Comment #9 from Jan Vesely <jan.vesely at rutgers.edu> ---
hm, I thought I sent this out yesterday...

the luxball issue should be fixed by 06bf56725db1827dfcb86b1d0bcd71d195fda1d2
("radeonsi: Bump number of allowed global buffers to 32")

the indigo benchmark might be just manifestation of earlier memory corruption.
it has been the case before that OpenCL apps don't allocate large enough buffer
for device name [0,1]. clover uses rather lengthy device names (~80 chars in
your case).
you can try modifying the name string in
src/gallium/drivers/radeonsi/si_get.c:964 to see if helps hide the issue.
