System hang: Problem with /build/buildd/linux-rt-2.6.28/arch/x86/kernel/signal_32.c [Was: dpkg crashes GNOME on UbuntuStudio 9.04]

This is a known bug and there is bug lodged here.

https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/363478/
I have appended the details below to the bug report.

Since the UbuntuStudio is unstable on my notebook then I shall use the
non-realtime kernel for the timebeing, and shall consider using the next
release of UbuntuStudio.

A shame because I am really impressed with the visual layout of Studio.
Gnome looks very nice on it.  Is there a easy way to have the same
UbuntuStudio layout/theme on Ubuntu?  Can I download the theme from
somewhere?

Best regards, s.
