Long ago I tried to figure out what IPS was doing on that particular machine, and at the time it seemed to be always thermally limited as soon as the GPU became active. So without tracing the IPS stuff again I can't actually say with 100% certainty that there isn't any change in the behaviour. I might do that at some point if I get bored enough. I did re-read the patch several times, but I still can't spot any functional changes in there.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
