I saw this when booting the machine (/dev/hdc is my ide dvd burner)
| Code: | ACPI: PCI Interrupt 0000:05:0c.0[A] -> Link [APC2] -> GSI 17 (level, low) -> IRQ 225

Any ideas? Is my burner probably broken, something on the mobo, or is it maybe software related :S |

I have seen these messages on a few machines that have perfectly good working dvd burners on so it may be a false alarm.

I would be a little worried about:
What is hdparm telling you? |

| Code: |
# hdparm /dev/hdc
/dev/hdc:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument

Whats the HDIO bit about  , and ya apparently no DMA, damn. |

From here:
| Quote: | HDIO_GETGEO
Returns the BIOS disk parameters in the following structure:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
A pointer to this structure is passed as the ioctl(2) parameter.
The information returned in the parameter is the disk geometry of the drive as understood by DOS! This geometry is not the physical geometry of the drive. It is used when constructing the drive's partition table, however, and is needed for convenient operation of fdisk(1), efdisk(1), and lilo(1). If the geometry information is not available, zero will be returned for all of the parameters. |
In other words, the HDIO_GETGEO error shouldn't really matter.
Assuming you have enabled dma support in your kernel, have you tried enabling it manually? |

A guick google search on 'cdrom_decode_status: status=0x51 { DriveReady SeekComplete Error }' turns up numerous results; it seems to be an error most commonly caused by aborting certain commands accessing the cdrom drive.
Does this error show on every boot? From what I gather, it could be a one-time thing. |

| I have noticed it at least twice now. I have reboot since those two though. |

| It seems to be a bug in the kernel ide-driver: see this and this. There seem to be some suggestions on fixing it as well; however, I have no idea if these work. |
