Trying to allocate it better.

This is a kernel bug <https://bugzilla.kernel.org/show_bug.cgi?id=42876> which says that all 3.2 and 3.3 kernels will crash as soon as the nouveau kernel module is loaded. I don't know if other NVIDIA cards of the NVC0 generation are affected as well.

The good news, not noted in the upstream bug: the issue is resolved in 3.4rc2 at the latest. Verified on Fedora 16.

Ubuntu 12.04 is already in the kernel freeze phase prior to the release, so the OOTB experience will likely remain broken for all users with a GTX 550 Ti. The workaround is to prevent nouveau from loading and to use vesa instead.

Status changed to 'Confirmed' because the bug affects multiple users.

similar issue but generally can reach the desktop using nomodeset and install and reboot using nomodeset to desktop but once the nvidia proprietery driver is installed I am then unable to boot to login screen even adding nomodeset

This is completely unrelated to this bug. 'nomodeset' effectively prevents nouveau from loading, hiding the issue. This bug is about nouveau in Precise kernel (well, for other reasons in Oneiric too), not about the Nvidia blob. 'nomodeset' has no effect on the Nvidia proprietary driver, because it doesn't support kernel based mode setting anyway.

Many Thanks germulvey.

While technically this does not fix the bug. It has triaged it for me to the point I have a working system.

I shall post in the related Ubuntu Forum threads this as a possible short term measure to bypass the impasse the bug causes on installation.

I agree with Ilja that this is a workaround not a fix though.

Similar bug for me, but I cannot even boot into a terminal. There is just a blinking cursor, after 1 minute a 2-seconds black screen and then a faster blinking cursor.

I am experiencing the same error. I try to load the 12.04 Live CD and after I get the following message
[drm] nouveau xxxxxxx Attempting to load BIOS image from PRAMIN
it just hangs.
In case you want me to provide you with a log please advise, since the CD hangs during loading and I am not sure whether I can do anything at this point.

I'm seeing the same thing here. I don't see any message at all, just blinking cursor in the upper left corner of the screen.

I should add that 10.04 LiveCD booted fine.

Is this still occurring on Ubuntu 13.04 "Raring Ringtail"?
