Sapphire 4850X2 Random Crash
This is my first post here, so forgive me if I'm not in line with the local customs...
I recently had to change my mobo on my workstation, and decided to upgrade the GFX card as well (previously, an Nvidia 8600GT was perfectly rocking the box). Considering the price (150€), I bought a Sapphire 4850X2 - but didn't know the ATI linux driver support was so poor (I promised myself 10 years ago never to buy ATI again after some nightmarish driver experience, things didnt change much it seems...)
Well, I suceeded in having Xorg launching (with this card, I HAVE TO enable crossfire, and if I don't, I only get a black screen and a PC lockup). I had to disable compositing as well (it froze the PC)
The problem is, as soon as the card get a bit of stress, either the PC reboot or freeze. There is not enough time for the system to write any log. For example, Google Earth crash the machine after 30 seconds of exploration.
Not to mention the system is perfectly working using any catalyst version under Windows XP.
System is Mandriva 2009.1
Linux localhost 220.127.116.11-desktop-1mnb #1 SMP Thu May 14 14:14:48 EDT 2009 i686 AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ GNU/Linux
Catalyst is patched 9.4 (9.5 didnt compile, even with the 2.6.29 patch)
Using KDE4 (but any DE will freeze in the same random way).
If anyone can help me narrow the problem, I would be grateful.
Thanks in advance !
