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 - dmesg -c > boot.dmesg.2; the screen freezes between 5 and 6 seconds after boot - dmesg > boot.dmesg.2.after_resume: dmesg after a suspend/resume cycle</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>
