Re: T40 bootloop on CAM status: Command timeout on both 10.1 and -CURRENT

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?

Regards,
Pietro Sammarco
