Without any success. Bug happens not only after suspend-resume cycle, sometimes it just happens without any particular activity, for example when I'm reading emails. Suspend-resume is just fastest way to reproduce this, for my x220 it's taking just couple suspend-resume cycles. I have tried to disable turbo-mode, and even set GEN6_RP_CONTROL to zero, so it's something deeper. Also I cannot find any lightweight magic sequence for returning gpu into sane state which can be used in watchdog. When bugs happens, gpu generates bunch of GEN6_PM_RP_UP_EI_EXPIRED | GEN6_PM_RP_UP_THRESHOLD events. Seems like some its internal state is broken and gpu thinks that it's extremely busy. Is there any way to examine or reset this state?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
