I wanted to work a little bit with that kernel to see how power consumption would improve so I compiled the same kernel but with the debug patch reverted (commit cf6e97774936be7e47eb2c0805b14db6412c14ae) But then, with this kernel: - with enable_psr=0 at boot : OK - with enable_psr=1 at boot: intermittent freezes like described before. The problem doesn't go away when I later set enable_psr to 0 (/sys/module/i915/parameters/enable_psr). I could consistently reproduce the problem. I see the debug patch also commented something related to timing. I'll try to keep only those comments and remove the verbose stuff and see if the problems goes away.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
