/*0 means you are going to do bounce buffering a lot, which seems
* DMA addressing mode.
* 0 : 32 bit addressing for all chips.
* 1 : 40 bit addressing when supported by chip.
* 2 : 64 bit addressing when supported by chip,

#define SYM_CONF_DMA_ADDRESSING_MODE CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
I will configure â0 : 32 bit addressing for all chipsâ for the RC8. Maybe this is the solution.
generally like a bad idea.
But why are we talking about the sym53c8xx driver now? The last issue
you reported was about video4linux allocations.
