I've been experiencing lockups with my NVidia TNT card, the NVidia drivers and Linux 2.4.x. I've done quite a lot of testing with different settings with the NVidia driver, with similar instability problems. I was discussing this problem on a mailing list and someone asked me if I had an AMD processor with a Via chipset. He mentioned that Win2k has a patch, which he experienced lockups with his video card until he applied it. He obtained some technical details of this patch which are below:
The following workaround for this issue prevents Memory Manager from using the processor's Page Size Extension feature and may affect the performance of some programs, depending on the paging behavior. This registry value also limits non-paged pool to a maximum of 128 megabytes (MB) instead of 256 MB.
Taken from MS Knowledge base article Q270715
The problem, in the case of win2k, is that memory that has been allocated by the video adapter driver is being corrupted.
How would something like this be applied to the Linux kernel? Does it sound like a valid solution? It was mentioned that this problem also occurs for the Matrox G400 card as well. I can supply more information if necessary, I just wanted to probe the LKML first as to where to go from here.
