Hello, I'm having detection problems with a CF to SATA bridge on a 2.6.30 kernel (2.6.30-1-orion5x). Platform is Orion SoC (DNS-323 Dlink NAS) The bridge is a "made in china" device with no real name : "CF TO SATA Converter" can be read on the package. They mention "Linux support whitout any additional drivers", and DMA and Ultra DMA support (if CF supports it) Tests have been done with a 128MB CFI et a 1GB CFII, no differences. dmesg gives : [ 1.960000] SCSI subsystem initialized [ 2.180000] libata version 3.00 loaded. [ 2.230000] sata_mv sata_mv.0: version 1.28 [ 2.230000] sata_mv sata_mv.0: slots 32 ports 2 [ 2.240000] scsi0 : sata_mv [ 2.240000] scsi1 : sata_mv [ 2.250000] ata1: SATA max UDMA/133 irq 29 [ 2.250000] ata2: SATA max UDMA/133 irq 29 [ 2.770000] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 2.800000] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x2) [ 8.280000] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 8.310000] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x2) [ 8.310000] ata1: limiting SATA link speed to 1.5 Gbps [ 13.790000] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 13.820000] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x2) [ 19.300000] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [ 19.300000] ata1: exception Emask 0x100 SAct 0x0 SErr 0x0 action 0x1 t4 [ 19.310000] ata1: edma_err_cause=00001000 pp_flags=00000000 [ 19.820000] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 19.840000] ata2.00: ATA-7: SAMSUNG HD103UJ, 1AA01118, max UDMA7 [ 19.840000] ata2.00: 1953525168 sectors, multi 0: LBA48 NCQ (depth 31/32) [ 19.870000] ata2.00: configured for UDMA/133 (I have the system root on a regular samsung disk attached to the second SATA slot) loaded modules related to storage : sd_mod 34340 3 sata_mv 29300 3 libata 169188 1 sata_mv scsi_mod 151332 2 sd_mod,libata Looking at libata options I saw : parm: dma:DMA enable/disable (0x1==ATA, 0x2==ATAPI, 0x4==CF) (int) I then tried option libata dma=3. No luck, same error log. I'm unsure if the problem comes from the orion architecture (marvell low-level sata driver ?) or is generic with 2.6.30 (I don't have SATA PC hardware here to disambiguate that). Any hints, directions I could look for are much appreciated !
