We have a series of machines that use CF as a boot media. Since upgrading to 2.6.20 (tried .9-.14), system will boot (from the flash media) but then fail to initialise the same media. Here is the dmesg from 2.6.20.14: ata_piix 0000:00:1f.2: version 2.00ac7 ata_piix 0000:00:1f.2: MAP [ P0 P2 P1 P3 ] ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (level, low) -> IRQ 19 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ata1: SATA max UDMA/133 cmd 0xFA00 ctl 0xF902 bmdma 0xF600 irq 19 ata2: SATA max UDMA/133 cmd 0xF800 ctl 0xF702 bmdma 0xF608 irq 19 scsi0 : ata_piix ata1.00: ATA-0, max MWDMA2, 990864 sectors: LBA ata1.00: ata1: dev 0 multi count 0 ata1.00: applying bridge limits ata1.00: configured for MWDMA2 scsi1 : ata_piix ATA: abnormal status 0x7F on port 0xF807 scsi 0:0:0:0: Direct-Access ATA CF CARD 512MB 2007 PQ: 0 ANSI: 5 SCSI device sda: 990864 512-byte hdwr sectors (507 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: write cache: disabled, read cache: enabled, doesn't support DPO or FUA SCSI device sda: 990864 512-byte hdwr sectors (507 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: write cache: disabled, read cache: enabled, doesn't support DPO or FUA sda:<3>ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 cdb 0x0 data 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1: port is slow to respond, please be patient (Status 0xd0) ata1: port failed to respond (30 secs, Status 0xd0) ata1: soft resetting port ata1.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80) ata1.00: revalidation failed (errno=-5) ata1: failed to recover some devices, retrying in 5 secs ata1: soft resetting port ata1.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80) ata1.00: revalidation failed (errno=-5) ata1: failed to recover some devices, retrying in 5 secs ata1: soft resetting port ata1.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x80) ata1.00: revalidation failed (errno=-5) ata1.00: disabled ata1: EH complete At this point the CF is inoperable. I've had no issue prior to 2.6.20. Is this a known issue? Is there a fix? -- View this message in context: http://www.nabble.com/CF-flash-IDE-failure-to-attach-with-2.6.20%2B-tf3939321.html#a11172839 Sent from the linux-ide mailing list archive at Nabble.com. - 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
