ASM1062 Serial ATA Controller (rev 01) As you can see, the 4-bay device needs Port Multiplier, in Windows 7 everything works fine (just saying, hardware is OK), all 4 disk drives are detected, but in linux not a single drive is detected! Here is dmesg output after powering 4-bay device off and on again: [ 1438.120315] ata11: exception Emask 0x10 SAct 0x0 SErr 0x10002 action 0xe frozen [ 1438.120323] ata11: irq_stat 0x00400000, PHY RDY changed [ 1438.120329] ata11: SError: { RecovComm PHYRdyChg } [ 1438.120340] ata11: hard resetting link [ 1438.842876] ata11: SATA link down (SStatus 0 SControl 300) [ 1438.842896] ata11: EH complete [ 1449.670083] ata11: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen [ 1449.670091] ata11: irq_stat 0x00000040, connection status changed [ 1449.670097] ata11: SError: { CommWake DevExch } [ 1449.670107] ata11: hard resetting link [ 1455.601866] ata11: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1460.599233] ata11.00: qc timeout (cmd 0xec) [ 1460.599247] ata11.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 1460.599255] ata11: hard resetting link [ 1461.090989] ata11: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1471.085591] ata11.00: qc timeout (cmd 0xec) [ 1471.085605] ata11.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 1471.085636] ata11: limiting SATA link speed to 1.5 Gbps [ 1471.085642] ata11: hard resetting link [ 1471.577336] ata11: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 1501.561182] ata11.00: qc timeout (cmd 0xec) [ 1501.561196] ata11.00: failed to IDENTIFY (I/O error, err_mask=0x4) [ 1501.561204] ata11: hard resetting link [ 1502.052960] ata11: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 1502.052980] ata11: EH complete Any ideas, how can I get this device working in linux?
