Greetings! You're not running the ide patches, are you? We're running 2.2.17 with the patches, and have found that we must use the ide-scsi interface to get verifiable backups. We still get apparently harmless error messages in the logs though. Here are our modules.conf entries: pre-install ide-scsi echo ide_scsi:1 > /proc/ide/hdc/settings post-install ide-scsi echo using_dma:0 > /proc/ide/hdc/settings pre-install ide-tape echo ide_scsi:0 > /proc/ide/hdc/settings pre-install st /sbin/modprobe -k ide-scsi We then use /dev/nst0. I believe these sysctrl parameters are only available with the ide patches. You might be able to replicate the functionality with module options if you're not using the patches.
