Roland Dreier, as per http://support.lenovo.com/us/en/products/Laptops- and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T440p?beta=false an update to your computer's buggy and outdated BIOS is available (2.36). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug. Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

In a default 14.04 install, the system is quite flaky: suspend doesn't work and doing lspci apparently corrupts memory (the system hits random weird failures and then freezes about 10 seconds after running lspci). If I blacklist the nouveau module then the system seems to work fine (suspend/resume is good and lspci doesn't cause problems).

[Kernel-packages] [Bug 1268669] Re: Lenovo T440p (Haswell/NVidia optimus gfx) flaky unless I blacklist nouveau
Does this issue not happen with prior releases or kernel versions? Also, would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 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.
