Dear List, since the switch to CONFIG_ATA=y CONFIG_ATA_ACPI=y CONFIG_ATA_PIIX=y, the ATA_PIIX driver manages both, internal sata disk aswell as cd/dvd rom. However I am being flooded with the error messages below (well they appear from time to time, dominating dmesg). This happens on kernel 2.6.22-rc5, I am copying relevant parts from dmesg: libata version 2.21 loaded. ata_piix 0000:00:1f.1: version 2.11 ata1: PATA max UDMA/133 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x000140c0 irq 14 ata2: PATA max UDMA/133 cmd 0x00010170 ctl 0x00010376 bmdma 0x000140c8 irq 15 ata1.00: ATAPI: HL-DT-ST DVDRW GWA4080M, AA26, max UDMA/33 ata1.00: configured for UDMA/33 ATA: abnormal status 0x7F on port 0x00010177 scsi 0:0:0:0: CD-ROM HL-DT-ST DVDRW GWA4080M AA26 PQ: 0 ANSI: 5 sr0: scsi3-mmc drive: 24x/24x writer cd/rw xa/form2 cdda tray sr 0:0:0:0: Attached scsi CD-ROM sr0 sr 0:0:0:0: Attached scsi generic sg0 type 5 ata_piix 0000:00:1f.2: MAP [ P0 P2 XX XX ] ata_piix 0000:00:1f.2: invalid MAP value 0 PCI: Setting latency timer of device 0000:00:1f.2 to 64 scsi2 : ata_piix scsi3 : ata_piix ata3: SATA max UDMA/133 cmd 0x000140d8 ctl 0x000140f6 bmdma 0x00014020 irq 0 ata4: SATA max UDMA/133 cmd 0x000140d0 ctl 0x000140f2 bmdma 0x00014028 irq 0 ata3.01: ata_hpa_resize 1: sectors = 234441648, hpa_sectors = 234441648 ata3.01: ATA-7: ST9120821AS, 7.01, max UDMA/133 ata3.01: 234441648 sectors, multi 16: LBA48 NCQ (depth 0/32) ata3.01: ata_hpa_resize 1: sectors = 234441648, hpa_sectors = 234441648 ata3.01: configured for UDMA/133 ATA: abnormal status 0x7F on port 0x000140d7 the actual errors: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 51/24:03:00:00:20/00:00:00:00:00/a0 Emask 0x1 (device error) ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 ata1.00: (BMDMA stat 0x5) ata1.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x25 data 8 in res 00/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x2 (HSM violation) ata1: soft resetting port ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 ata1.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 00/24:03:00:00:20/00:00:00:00:00/a0 Emask 0x2 (HSM violation) ata1: soft resetting port ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 ata1.00: (BMDMA stat 0x5) ata1.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x25 data 8 in res 00/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x2 (HSM violation) ata1: soft resetting port ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 ata1.00: (BMDMA stat 0x5) ata1.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x43 data 12 in res 00/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x2 (HSM violation) ata1: soft resetting port ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 51/24:03:00:00:20/00:00:00:00:00/a0 Emask 0x1 (device error) ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: (BMDMA stat 0x5) ata1.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x25 data 8 in res 51/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x1 (device error) ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 ata1.00: (BMDMA stat 0x5) ata1.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x43 data 12 in res 00/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x2 (HSM violation) ata1: soft resetting port -- Sometimes, there's a moment as you're waking, when you become aware of the real world around you, but you're still dreaming. - 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
