Thank you for taking the time to report this bug and help to improve Ubuntu.

The report includes no information about the actual crash, so this is impossible to debug. Did apport not manage to collect a backtrace for this crash (because plymouth crashed too early, maybe)?

I see you have the radeon KMS driver loaded but are booting with vga=791. Is the problem reproducible if you drop this vga= option from your boot commandline? Is it reproducible if you boot without 'splash' (which is not the default for new installations of 10.04 LTS server)?

plymouth crashed very early in the boot process, so i presume, apport did
not manage to gather any other information.

I've droppen the vga=791 and splash from the defoptions line in menu.lst,
that completely kills my console (only ssh login possible)
Dropping only the splash from the menu.lst still crashes plymouth (directly
after cups boot).

Can i manually collect a backtrace you can use and if yes, please send me
the appropriate commands. (direct debugging also possible, contact me via
jabber @ <email address hidden>)
