Dear maintainer, just to give you some more information:
The error also occurs using the weekly build: http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/debian-testing-amd64-CD-1.iso Further I thought it could be usefull to know, that the error occurs at all possible three SATA-Mode-Configurations: - RAID and AHCI result in exactly the same error-message - Native IDE result in the same error, just that ata8 and ata8.00 are replaced by ata2 and ata2.00 within the message
