Daniel, we prefer to have those files attached as separate files to
each bug report, since that makes triaging much more efficient. I'm
attaching the files from the .tgz linked to in the description here.

I'm not sure, but I think the more the merrier, since I think there is
usually a mix of relevant and irrelevant data in the dump and more
dumps makes it easier to filter out the relevant part. That being
said, I haven't heard a lot back from upstream about the dumps we have
sent there, and I don't know how to read them myself.

Albert Damen has proposed a way to improve the usefulness of the
batchbuffer dumps in bug 447892, comment 23. That requires the very
newest driver from the xorg-edgers PPA,
https://launchpad.net/~xorg-edgers/+archive/ppa .

Meanwhile, Brian Rogers have made some interesting findings at a
similar bug, http://bugs.freedesktop.org/show_bug.cgi?id=24825 . It
looks like downgrading the kernel should work, but he hasn't found the
commit that triggers the freeze yet. You could check if you can
reproduce his findings using the mainline kernels (i.e that 2.6.30
does not freeze while 2.6.31-rc3 freezes). That may indicate that
you're having the same problem. See
https://wiki.ubuntu.com/KernelTeam/MainlineBuilds for more information
about the mainline builds. (Downgrading the kernel cannot be done
while running xorg-edgers, since xorg-edgers requires a recent kernel)
