So I'm not getting the function call I wanted. Assuming that the error occurred at some point, I'm looking for "intel_cpu_fifo_underrun_irq_handler" and the commit just before this, causing the underrun. I tried to debug regardless, but it is a very difficult to find the commit causing this issue considering that there are 500 odd commits in the trace. Can you please try having a script running in background to keep dumping the trace to a log file(or may be different files if there's too much logs) just to ensure we're not missing any trace and with this we'll try to catch the function call for fifo underrun.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
