By the way, is it possible to collect any freeze data which might shed a light on a possible cause?
When I boot after a unclean/hard reboot and log into a Unity session, I see a number Apport dialog windows (3 to 5 usually). However, when I press 'OK' on one of them, enter my password, it starts collecting data related to previous unclean resume/restart. But once it's done, and I want to submit the data collected and press the button, the dialog window just closes and nothing else happens. The rest 2–4 windows can be just closed, after the 1st they do nothing. Is the data collected stored anywhere so that I could take it from there and submit it manually? Or does it just mean that nothing useful had been collected? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1315277 Title: [Dell Inspiron 1525] Trusty freezes on resume from suspend Status in “linux” package in Ubuntu: Incomplete Bug description: The issue hit the system right after uprading from Saucy to Trusty. Ubuntu Trusty freezes on resume from a suspend on a DELL Inspiron 1525 machine. All I see is just LEDs for disk (just blinks for a moment) and wifi (stays lit), fan noise and a black screen. No mouse cursor, no nothing. The magic SysRq (+REISUB) does nothing; a hard manual reboot by pressing the power button is necessary. The problem is gone if booting with a 3.11-20 kernel left from Saucy. The issue is present, however, at least with 3.13.{8,11} and 3.14.{1,2} mainline kernel builds. I haven't tried 3.15rc, though, since it boots with a totally black screen and I have no idea how to bypass it; and my Broadcom wifi driver fails to build with 3.15rc too. I believe it is the same bug as Bug #1310823 and am just reporting this in order to upload my system's data.
