Comment 13 for bug 182996

Exactly the same problem here on a Debian SID system (I do know that this is a Ubuntu bug-forum. However, we are relatives, right :-))

Kernel: 2.6.24-1-amd64 #1 SMP

here´s a cut from my syslog

kernel: hda: status error: status=0x59 { DriveReady SeekComplete DataRequest Error }
kernel: hda: status error: error=0x00 { }
kernel: ide: failed opcode was: unknown
kernel: hda: drive not ready for command

dev/hda/

ATAPI CD-ROM, with removable media
        Model Number: BENQ DVD DD DW1620
        Serial Number:
        Firmware Revision: B7W9

Two identical sata drives are conneted as well
dev/sda and /dev/sdb

/dev/sda:

ATA device, with non-removable media
        Model Number: SAMSUNG HD501LJ
        Serial Number: S0MUJ13P220357
        Firmware Revision: CR100-10
        Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5

At the moment I use the solution suggested by pvdeynse (hdparm -w1 /devhda).
I would be interested to know what´s causing these error messages and how to get rid of them without a drive reset after boot.
