I get this too. Playing with IRQ allocations helped a bit, underclocking
the system helped a bit, and replacing the motherboard eliminated the
problem (but replaced it with others). That "Xid" error is the key by
which you'll find lots of threads about the exact same problems by
people trying to use OpenGL for games, and other cases...
I think it's some kind of DMA/IRQ/shared-IRQ and Linux kernel/Nvidia
driver co-operation issue that basically has no total solution. Some
people just are luckier than others (I'll leave it for you to decide
which group - the ones getting consistent lockups under certain
circumstances, or those getting infrequent random crashes).
