Hi Edwin,
Since you didn't attach the dmesg I can't trouble what had happen.
May be you can try the follow kernel parameter and tell us the result
all_generic_ide
libata.dma=0
Regards,
Punky

I'm trying to turn off DMA for 0.6 on a WRAP board with
kernel /vmlinuz root=LABEL=ROOT_FS console=ttyS0,38400n8 ide=nodma
but the errors (and lengthy boot time) still persist.
Am I missing something?
Edwin
