>Description:
To get access to the IDE DVD device, via the CAM SCSI subsystem.
I use the following lines in my kernel config file:
device atapicam
device scbus
device cd
device pass

On boot, when the kernel reach the CD/DVD drive, the following messages 
appear and then the system freeze.

acd0: DVDR <NEC DVD RW ND-3500AG/2.16 at ata5-master UDMA100
cd0 at ata5 bus 0 target 1 lun 0
cd0: <_NEC DVD_RW ND-3500AG 2.16>
Removable CD-ROM SCSI-0 device
cd0: 33.000 MB/s transfer
cd0: cd present [1*2048 byte records]
Interrupt storm detected on "irq10:atapci1";
throttling interrupt source

After here I put the power button a few times and the kernels says something like that ACPI is not ready.
Note that I have upgraded to 5.3-RELEASE from src via CVS from 5.2.1

If I can help by giving you more information let me know.
Best regards

>How-To-Repeat:
In my case, recompile the kernel with the CAM interface. Add this to the kernel config file.

device atapicam
device scbus
device cd
device pass
