Yes, according to my coworker, Windows Embedded boots fine. And the system boots via the card, with syslinux loading the kernel/initrd from the card, so I don't know why it wouldn't be ready. As I mentioned before, 'sdparm --command=capacity /dev/sda' initially fails, but will succeed after 'sdparm --command=start /dev/sda'. However, even though capacity works after the start command, attempts to access the card continue to fail (e.g fdisk -l /dev/sda).

kernel cant access SATA adapter device
Hi, I've got a SATA adapter for a SD card in a Dell Poweredge R610. The BIOS can see and boot the sdcard, (to Windows, or using syslinux/extlinux), but when it hands over control to the Linux kernel, the kernel cannot access it. Here's an excerpt from dmesg: scsi 0:0:2:0: Direct-Access ATA FC-1307 SD to CF 1.1 PQ: 0 ANSI: 5 sd 0:0:2:0: Attached scsi generic sg3 type 0 mptsas: ioc0: mptsas_free_fw_event: kfree (fw_event=0x8801ab1ad8c0) sd 0:0:2:0: [sdc] Spinning up disk .not responding... sd 0:0:2:0: [sdc] READ CAPACITY(16) failed sd 0:0:2:0: [sdc] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 0:0:2:0: [sdc] Sense Key : Not Ready [current] sd 0:0:2:0: [sdc] Add.

If I put the SD card in a USB adapter, it works, and I was able to access the SD card via the SD adapter in another machine. But our production machines are dell's, so I really want to get it working there. I've attached more complete debug info from booting and existing CentOS 6.4 install with the card installed, and a rdsosreport from an attempt to boot Fedora 20 Alpha. Any help or suggestions greatly appreciated.
