The lockup always occurs in NVSync() and it's always the result of some call from XAA. Sometimes it's XAAGlyphs(), other times it's XAACopyAreaFallback(), or something else but it always winds up looping in NVSync(). What would cause the card to not process the accelerator FIFO?

A card lockup usually means that there is a bug somewhere (in the driver, or in the hardware). Saying you have a card lockup is as vague as saying you have a segmentation fault. That in itself doesn't help debugging the code. Stephane </PRE> </BLOCKQUOTE> </BODY> </HTML>
