Same problem here, ubuntu studio as well.
In fact I cannot upgrade packages anymore, since it crashes everytime it tries
to install openoffice.org-emailmerge.

I've fixed this problem also by building my own kernel. I used the
vanilla 2.6.30 sources from kernel.org, copied the .config from
2.6.28-rt and issued:
make oldconfig
fakeroot make-kpkg --initrd kernel_image kernel_headers
There's a bug with dkms and nvidia-common when it's ran as a post
There's a patch here for a similar problem in 2.6.24:

I'm also getting random app lockups on disk access in Ubuntu Studio 9.04
kernel 2.6.28-3-rt, but on an ext3 volume. They are not very frequent,
once or twice a day. I've attached the kernel crash info from syslog.

Looks like the same crash that I was getting with that Kernel, so it
doesn't seem to be file system specific. I'm still using the stock
2.6.29.4 Kernel that I built with make-kpkg and have not had any
crashes. It gets fairly good latency response (only occasional
underruns with 5ms latency on my
I ended up building my own kernel using make-kpkg and stock Linux
2.6.29.4, with the .config from /boot/config-2.6.28-3-rt. No lockups in
several days now, so whatever issue I was having is fixed in at least
2.6.29.4. I have not tested latency with this kernel, so I'm not sure
how well it performs
