Hmm... you don't happen to use a Matrox Mystique?
I've been getting these lockups with all XFree 3.9.x and XFree 4.0 with
any kernel (tested with a few 2.2 and 2.3).

It also occurs when moving windows around or scrolling in netscape.

But I don't get complete lockups, it's only X that hangs, everything else
runs just fine.

This may be what I thought from the beginning, a bug in XFree.
But maybe it's a bug in kernel thats showing up more clearly now.
