I attempted to restart my Lenovo T400, and my laptop just sat there on the desktop, not responding. so after a hard restart, there was this error that there was some sort of error with my "temporary folder". i thought nothing of it and skipped whatever setup or fix it was attempting to do. now my system boots up to the ubuntu screen, but then goes straight to this black TTY/Kernel screen. tried a couple options off of here to no avail, and I've only seen one problem that's remotely similar to what I'm seeing here..
Ctrl+Alt+F7 takes me to a blank black screen and nothing happens.
after logging into my username, it tells me:
"no talloc stackfram at ../source3/param/loadparm.c:4864, leaking memory"
sudo dpkg --configure -a
as a first shot.
