Hi Christopher, I haven't done kernel bisect, but instead did a lot of googling, and found this bug:
https://bugzilla.kernel.org/show_bug.cgi?id=42977 which is affects some other Toshiba Tecra laptop, but have same symptomps and moreover, the proposed workaround with nox2apic kernel commandline option seems to be working for me! Apparently, the problem has been present in the kernel for quite some time, which really confuses me, as I'm pretty sure suspend/resume worked for me for at least some time before; unfortunately I don't know the good kernel version to start with, which makes bisecting impossible. Also, out of curiosity I tested my laptop with a live version of debian-7.6.0, and it also hangs with same symptomps. ** Bug watch added: Linux Kernel Bug Tracker #42977 http://bugzilla.kernel.org/show_bug.cgi?id=42977 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1362958 Title: [Toshiba Tecra R850-14Q] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1362958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
