Laptop on AC, undocked, psr=1, fbc=0 - at boot after modeset, screen freezes, like in <a class="bz_bug_link bz_status_NEW " title="NEW - PSR screen freeze after modesetting" href="show_bug.cgi?id=91436">bug 91436</a> - a suspend/resume cycle doesn't help with "unfreezing" the display. At resume the display will show the current laptop state (eg. if I suspend the laptop when the screen is frozen at the luks password prompt, at resume I'll see X's login screen), but the screen will freeze instantly again (can't see the mouse pointer moving). - laptop is responsive though, ssh'ed into it; see attached dmesg with debug output (boot + 2 suspend/resume cycles). - reboot -> oops</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>
