Hi this is digitman, I have repeapedly tried to install debian on my amd64 box which has Nvidia-sli chipset and pci-express ati x300, video card . it will install but if you try to open mozilla or some big app it locks the system and if you try and install kde and login to it forget it locks up ? I need help . I think its my pci-express card possiby ... thankyou digitman

Interesting. I had the exact same thing happening to me. nvidia nforce4 chipset and an ati x300 PCIe card. Install went fine and I could use some apps but when I started firefox or mozilla the system would lock up hard (not just X. The box wouldn't even respond to pings anymore). Tried it a couple of months ago with debian etch and sid. I didn't have time to fool around back then since I needed my computer to actually work, so I didn't do much in terms of trying to figure out what was going on. I have since then installed ubuntu dapper (beta) and it works fine. I'm even running debian (sid) in a xen virtual machine where I didn't come across this problem so I figured it's been a bug in a package that's since been updated (then again a virtual machine is probably quite a different matter).

Not much help here, I know. Just thought I'd let you know it's not just you experiencing this problem.

edit: oh, and btw: I tried both the i386 and amd64 version of etch. Same result.
