What is the memory configuration used in KBL & SKL boards. There were few known WA to solve potential fifo underrun issues, Patches got merged for same recently. Can you please make sure that following series is present, and tryout if issue is still reproducible. <a href="https://patchwork.freedesktop.org/series/46481/">https://patchwork.freedesktop.org/series/46481/</a> one of the major different between SKL and KBL is IPC, I would also like to check if issue is reproducible after disabling IPC. which can be done by writing #echo 0 > /sys/kernel/debug/dri/0/i915_ipc_status In parallel I'll try to check if there is any known KBL specific WA missing.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
