Comment 35 for bug 419328

The primary reason I wrote my comment was because I observed my X server hanging. Indeed, the reason I found this bug was because I get the same stack trace in dmesg showing where the deadlock occurs.

It is not known to me whether display corruption is related or not, and in my first comment, I indicated that it might or might not be the same bug. If it's makes things easier, let's ignore the display corruption and assume it's unrelated.
