bhaskar, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.15-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-a15 ** Tags added: latest-bios-a15 ** Changed in: linux (Ubuntu) Importance: Low => Medium -- 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/1315027 Title: [Dell Precision M6600] Suspend puts laptop in state requiring hard power down + power up Status in “linux” package in Ubuntu: Incomplete Bug description: At random (I estimate perhaps 20-25% of the time), when I suspend my Kubuntu 14.04 (upgraded from 13.10, not a fresh install) laptop, it blanks the screen, and displays a message such as that below on the text console. Then, instead of going to sleep, it remains powered up. In this state, nothing works to get back control, not Ctrl-Alt-Del, Ctrl-Alt-Backspace, Ctrl-Alt-F2 (or other function key), not ^C. The only way I have found to get control is to hold the power button down, which is a power-down and then power-up. Message on console is: [40066.396632] PM: Syncing filesystems ... done [40066.767832] PM: Preparing system for mem sleep [40066.768398] i2400m_usb 2-1.5:1.0: firmware i6050-fw-usb-1.5.sbcf: Cached [40066.768473] Freezing user space processes ...
