If I hibernate while my USB hard drive is mounted, I consistently get filesystem errors on resuming. Booting with i915.modeset=0 prevents the errors. I've already provided some information on #770754. Adding the output of lspci-vnn here.

Sorry, proper link: bug 770754
Please test if any of mutual exclusive options listed below make issue gone (remember to remove i915.modeset=0) : pcie_aspm=off pcia_aspm=force
Neither option prevented the errors.
I believe this was eventually narrowed down to a console blinking cursor issue. If you are still seeing this, please reopen and list the newest kernel it happens with.
Indeed, the problem seems to have gone away.
