It did, as documented on #1007138. On older releases, the system would sometimes boot and sometimes not. #1007138 mentions hanging 9 out of 10 times but I think on raring it hung something like 1 out of 4. This is, of course, a very rough statistic.
On Saucy, it never seems to boot without pci=noacpi. Could be that if I spent a couple of hours just rebooting, it might work :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1250027 Title: 10de:1056 [Lenovo ThinkPad T420s] Fails to boot using nvidia drivers Status in “linux” package in Ubuntu: Incomplete Bug description: Booting a ThinkPad T420s with discrete graphics enabled in the causes a hang during the boot.
