--- Comment #9 from Jan Ziak 0xe2.0x9a.0x9b@gmail.com --- Created attachment 124155 --> https://bugs.freedesktop.org/attachment.cgi?id=124155&action=edit S_03093C_OFFCHIP_BUFFERING(offchip_blocks) if >= CIK
This patch fixes the issue on my R9 390.
The code is just a guesswork. Maybe it should be (2*offchip_blocks-1) instead?
