dmesg with a nice error log

hi,
after updating to mesa, ati-dri and mesa-libgl 9.1.2, everything work but when
launching "eclipse juno" (even a fresh install) the monitor turn off, sometimes
the system doesn't respond, sometimes the montor keep turning on and off, GUI
in freezed but i can still use virtual consolle. No problem with steam, bzflag,
flash, older version of eclipse or other java program. Also GPU extensive test
have been done on windows system with no fault.

Work-around is falling back to 9.1.1

my board:

$ lspci | grep -i VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Pitcairn PRO [Radeon HD 7850]

here you will find attached dmesg and xorg log during one of the (rare) times
when monitor was going on and off. Xorg seems to stop just before the system
goes in this "loop state"
anyway dmesg seems to catch the problem
