Tested with kernel 3.2.0-31.50, it still hanged on resume. Need to press the power button for a while to turn it off. No related log can be found.
And on the first boot after hanged, the system may fail to enter graphic mode. The screen is blank, but system still responds to keyboard input. Error messages like this can be found in the log: [drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD) [drm:evergreen_resume] *ERROR* evergreen startup failed on resume -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997038 Title: can't wake up from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/997038/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
