[Bug 1230041] Re: i915_hotplug_work_func cause system crash
databill, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (3.22). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
