--- Comment #2 from Christian Zigotzky (chzigotzky at xenosoft.de) ---
Error message without limitation to 3.5G RAM:

[   25.654852] bttv 1000:04:05.0: overflow 0x00000000fe077000+4096 of DMA mask
ffffffff bus mask df000000

The kernel configured the bttv card for DMA in the upper region of RAM but the
device believes that it only supports 32-bit addressing.
