Tejun, et al, Hardware: Norco DS-1220 SATA enclosure (sil2134 card w/ 4 PMP/direct ports, enclosure is 2x sil3726 (5 disks each), and then 2 direct SATA ports. (also have 2x SATA internal, on ata_piix, md raid1, that's working fine... those are sd[ab], ata[12].nn, scsi[01]) Kernel: 2.6.18.6 + libata-tj-2.6.18.1-20061020. Issue: Disks in DS-1220 show up, kinda, but don't work. Errors reading / writing blocks. Tried a single disk in both a PMP port and a direct (non-sil3726) port.

I'm more than willing to be your guinea pig, testing whatever. Would love this wonderful hardware to work well for others eventually with less pain. Thanks!
