I've still been battling to get this hardware detected with any of the drivers mentioned previously except the newer libata piix driver. However when using the old driver and using "all-generic-ide" and "irqpoll" as kernel parameters I now have the device being detected albeit complaining about lost interrupts and DMA timeouts. Here is the output from the hdparm -I /dev/hda that you requested: /dev/hda: ATA device, with non-removable media Model Number: CF CARD 512MB Serial Number: CF512 0001943B Firmware Revision: 20070131 Standards: Likely used: 5 Configuration: Logical max current cylinders 983 983 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 990864 LBA user addressable sectors: 990864 device size with M = 1024*1024: 483 MBytes device size with M = 1000*1000: 507 MBytes Capabilities: LBA, IORDY(may be)(cannot be disabled) bytes avail on r/w long: 4 Queue depth: 1 Standby timer values: spec'd by Vendor R/W multiple sector transfer: Max = 1 Current = 1 DMA: mdma0 mdma1 *mdma2 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns HW reset results: CBLID- below Vih Device num = 0 Many thanks for your help. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
