Hi, I just added 5 2TB drives in an external enclosure that came with a PMP (so I have a single eSata cable going to some internal sil3124). 02:02.0 Mass storage controller: Silicon Image, Inc. SiI 3124 PCI-X Serial ATA Controller (rev 01) PMP is detected as ata6.15: Port Multiplier 1.1, 0x1095:0x4726 r31, 7 ports, feat 0x1/0x9 kernel: 2.6.31.6 2 logs below: 1) drive discovery and init (with some errors) 2) drive being killed with ata6.05: unsupported device, disabling sd 7:0:0:0: [sdm] Add. Sense: Unrecovered read error - auto reallocate failed Any idea if this is just one of those erratas between the sil 3124 and the PMP that is so that it won't even work long enough to init the drives? Thanks, Marc This is when I plugged the eSata cable in on a running system: ata6: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0xe frozen ata6: irq_stat 0x00b40090, PHY RDY changed ata6: hard
