Bug Description
Binary package hint: sysvinit
I just reinstalled this box with today's karmic alpha-6 image (amd64). Live image works fine, but after booting the installed version I see some messages passing by, and then the screen powered off. Hard disk was grinding, and nothing happened for ten minutes, so I eventually rebooted. That didn't help either, so I rebooted again with i915.modeset=0 and finally saw that fsck of /home was going on (it's still ext3, so I suppose it's likely that the previous run just didn't finish).
Arguably I should have gotten usplash for this case, but even if I don't, there should be usable VTs during the boot phase, so that it's obvious what's going on.

After a followup boot where fsck wasn't running any more, I just get a 10 second phase of screen power-off.
I had exactly the same symptom some time ago when I debugged a new i915 driver and booted without initramfs. Back then the problem was that the fbcon driver did not get loaded. It looks like we have the same problem now, and fbcon should be loaded much earlier in the boot process?
