This has worked well for me on U5 for ages. The debug messages have also been there as long as I remember. The controller is limited to 128GiB disks in DMA mode so I have used up to 120G disks only and have not tried any bigger ones.

My U10 has addon PCI SCSI controller so I'm not testing IDE there. -- Meelis Roos (mroos@xxxxxxxx) -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
