Bug#275735: xserver-xfree86-dbg: Removing xlibmesa-dri library does not help either

[Frederic Lehobey <Frederic.Lehobey@free.fr>]

Package: xserver-xfree86-dbg
Followup-For: Bug #275735

Removing xlibmesa-dri does not prevent the lockups either (previously
in the thread around this bug xlibmesa-dri has been suggested as
possible root of the problem).

Should not this bug raised to release critical as it make XFree
unusable on iBook 2.2?  I do not know of any workaround.  Are the
original submitter and I the only people to experience it?  I
understand how difficult it is to track down such a bug for which we
do not know any deterministic way to trigger it (but it always occurs
after a few minutes XFree is running).  I am willing to help even it
seems to me beyond my current skills.

Thanks for your work,
Frédéric Lehobey
