This can't be. This log can't possible match the other one you gave me. In the /var/log/messages it showed the agp buffer being added and so on.
The only explanantion I can think of is that you're running _two_ X servers. The first one acquires the AGP device but the second fails to acquire, since the AGP device is already acquired by the first.
FWIW, I get that now always when I start the X server, then shut down
the X server and start it again. DRI will never work again, unless I
rmmod the radeon module manually before I restart the X server. Sounds like some initialization thing.
lsmod will show (before starting X, but after manually inserting agpgart
& radeon):
Module Size Used by Not tainted
radeon 102152 0 (unused)
agpgart 13904 1
after X is started: radeon 102152 12 agpgart 13904 3
and after X shutdown (and restart with dri not working): radeon 102152 0 agpgart 13904 3
after rmmod radeon the agpgart used count will be back to 0.
unsigned int cmd, unsigned long arg) (in drm_agp_tmp.h) returns an error, since dev->agp->acquired is still 1 (verified with some additional debug output).
I remember there was a bug which resulted in non-freeing the resources if the X Server was terminated, but I thought this was fixed some month ago?
