Bug Description
Using the stack from the PPA mentioned in Bryce Harringtons blogpost (http://
* i get a message that the kernel parameter is unrecognised at the beginning of the boot process
* usplash starts showing, and when the progress bar is at about 20% ( i assume that's when the X server starts), the screen turns black. you can see by the HDD activity, that the boot process probably continues just fine, except nothing is shown on screen.
This is on a Thinkpad T60 with ATI X1400 graphics.

Do you have something like cryptsetup hooking into usplash? Is the usplash screen higher resolution than normal? Can you ssh into the machine from another to obtain the dmesg output and /var/log/Xorg.0.log from the machine it happens by any chance? You can ignore the message about unrecognized parameter, it's because its a module and not available at the start because its not built into the kernel, but the parameter does get passed to the module later.
