I used the following script:
#!/bin/sh
TRY = 5
while [$ (TRY)-gt 0]; do
# Konqueror &
okteta &
kcalc &
kwrite &
TRY = `expr $ (TRY) - 1`
done
sleep 30
killall konqueror
killall okteta
killall kcalc
killall kwrite
If I set "hw.dri.0.debug = 1" the problem is not reproducing, even at very big
values of ${TRY}.
However if hw.dri.0.debug = 0 one pass reproduces the problem.
If I set "hw.dri.0.debug=1" _after_ the server hang, I see the message:

I try to apply this patch:
http://people.freebsd.org/ ~ rnoland/drm_radeon-copyin-fix-try2.patch
In my case the problem remains.
