Replacing the dodgy RAM module did the trick.



Thanks Dave. Any update on your problem Ken? I'm keen to hear whether you had crashes without the NVIDIA driver loaded.


Sorry, I got called out of town last weekend so I didn't get a chance to try this out yet..

As a follow-up to close out this thread. I only had a chance to test the nv driver for a short time before needing to go back to the xinerama capabilities of the Nvidia driver again. I subsequently had a severe crash that beat up the filesystem pretty badly so I did a data backup and a clean install of Gentoo/KDE3.5 (kernel 2.6.15-r1) along with the binary Nvidia driver (1.0.8178-r3) and have not had the problem re-occur since. The new install is using the same hardware and kernel config which has been stable for over a week of uptime now. This would lead me to believe my previous install suffered from some evil filesystem gremlin that had snuck in from an earlier crash and continued to pop up to cause havok versus a genuine kernel bug.

I appreciate the help and feedback in trying to get this figured out.

Thanks,
Ken
