I ignored this info first time, but I will ask now. Does this implies
that libthr is listed in Xorg ldd(1) output?
I use server build without hal support on 945GM(irq not MSI) and I do
not experience problems with drm/dri/OpenGL/xv or whatever other
protocol you name it.
Yes, if xserver is built with HAL support, I see it linked with libthr.
If HAL is disabled, it doesn't appear to be. I'm trying to remember
exactly what the reported issue was, but I think it was X crashing on
exit.
I can verify that that /is/ an issue. My first experience/experiment
with an nVidia card bit me this way. I built xorg w/o hal, and sure enough,
every time I left X, the drives started rumbling - then I got console
to see the message: xorg dumped core signal #.
So I always build it with hal - whether I use it or not. :)
