Hi,

Can anyone point me to a list of valid kernel parameters for backfire on x86?

I have a PC Engines WRAP 2C with IDE problems.
I've tried:
kernel /vmlinuz root=/dev/sda1 ro console=ttyS0,38400n8 ide_core.nodma=0.0

and

kernel /vmlinuz root=/dev/sda1 ro console=ttyS0,38400n8 ide=nodma

in my Grub but both result in:

ata1: lost interrupt (Status 0x58)

I know WRAP has problems with IDE DMA. How do I disable it?

Thanks,
