Ubuntu RT freezes on Boot

[Foster Benjamin W.]

I have a Sony VIAO  VGN-N38E

I have not been able to install Ubuntu_Studio from alt cd.

My Release is reported by sysinfo as 5.0
2.6.28-16-generic (#55-Ubuntu SMP Tue Oct 20 19:48:24 UTC 2009)
GCC Version 4.3.3 (i486-linux-gnu)

Genuine Intel(R) CPU           T2130  @ 1.86GHz
800.000 MHz

I also have Linux Kernel Linux-rt 2.6.28.31

I need desperately to run Rosegarden but the system freezes on startup 
when I boot the rt.

If anyone has any help to offer it woud be greatly appreciated.


Best Regards,
Foster
