Lockups are very rare (they come either during 30mins after boot or never) but I cat get them very quickly when using the framegrabber with ivtv driver. The ivtv driver itself works rock solid on older PIII system (btw, that PIII runs SMP kernel !). So I think there are definitely DMA problems with nforce2 boards under linux.
