Hey wolfgang,

thanks for getting back to me. Adding hint.ata.1.disabled="1" in /boot/device.hints indeed did the trick and allowed me to boot both 10.1 and 11-CURRENT, however this workaround has temporary solved my problem but brings up to another headache. I have planned to get a bay caddy and swap the cdrom drive with a 7.200 rpm SATA hdd, but doing this way disabling the second SATA channel I will be unable to achieve such a thing.

Is there a chance that the bay caddy ATA will work without the need to disable the second ATA channel?

I had the same problem on an ancient T42p. In my case, disabling the
second ata channel allowed me to boot.

I added the following line to /boot/device.hints:
