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update to your computer's buggy and outdated BIOS is available (2.36).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.

Thank you for your understanding.

Title:
  Lenovo T440p (Haswell/NVidia optimus gfx) flaky unless I blacklist
  nouveau

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a new Lenovo T440p laptop, which has a Haswell CPU and NVidia
  GPU in an "optimus" setup.  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).
