After the last kernel update I got a blank screen at boot. I'm not sure, but I think it happens when KMS kicks in. I think it's related to a broken EDID I've been fighting for months. The stop-gap measure I'd been using so far is to have a custom config in xorg.conf.d and booting to a DM, but that doesn't seem to work with the new kernel.
I get a ton of messages like this:

With syslinux it looks like this, right?
APPEND root=UUID=141d4661-1b1e-469a-9261-a64b812b6c7f ro video=LVDS-1:dDoesn't have any effect for me. I still can boot with 3.5 but not 3.6.

Hi,
Are you in autologin ? I have the same issue with Slim and autologin so i change Slim to LXDM and it is all the same. The connexion works perfect and when i put the autologin : black screen !
Any ideas ???

Huh? It's got nothing to do with my DM (I use LightDM). I get a blank screen without X. I was loading a DM at boot to work around this problem, but it required a custom xorg conf and the workaround no longer works.

I can confirm that this is definitely caused by KMS. It doesn't make any difference whether I'm using nouveau or the proprietary drivers, but I can get into a login prompt by adding nomodeset to the kernel parameters. It's been suggested to set the resolution manually like this:
video=VGA-1:1280x1024@75And that does set the resolution, but I end up getting a blank screen anyway.
I've switched to linux-lts for now, but obviously this is not a permanent solution. Does anyone have any idea of what I should do? There doesn't appear to by any definitive information about what to do when KMS fucks up.
