Hello,

I just added 
device atapicam
device scbus
device cd
device pass
to my kernel configuration, as per the manual page (atapicam (4)).

This comes on top of 
device ata
device atapidisk
device atapicd
device atapifd

When booting this kernel, a 4.9-PRERELEASE cvsup'ed today, the following
happens:

[snip]
IP packet filtering initialized, divert enabled, rule-based forwarding
enabled, default to deny, logging limited to 100 packets/entry by
default
IPsec: Initialized Security Association Processing.
ata1-slave: ATAPI identify retries exceeded
ad0: 9787MB <QUANTUM FIREBALL EX10.2A> [19885/16/63] at ata0-master
WDMA2

fatal kernel trap:

trap entry = 0x2 (memory management fault)
a0         = 0xfffffe400073903c
a1         = 0x1
a2         = 0x0
pc         = 0xfffffc000035ec50
ra         = 0xfffffc000035ec20
curproc    = 0xfffffc00006038e0
pid = 0, comm = swapper

panic: trap
[snip]

Booting the backup kernel, a 4.8-STABLE, a normal run looks like this:

[snip]
IP packet filtering initialized, divert enabled, rule-based forwarding
enabled, default to deny, logging limited to 100 packets/entry by
default
IPsec: Initialized Security Association Processing.
ata1-slave: ATAPI identify retries exceeded
ad0: 9787MB <QUANTUM FIREBALL EX10.2A> [19885/16/63] at ata0-master
WDMA2
acd0: CDROM <PCA123CD> at ata1-master PIO3
Mounting root from ufs:/dev/ad0a
savecore: no core dump
[snip]

The CD-ROM is a very old Philips PCA123CD.

Have I configured it wrong, or is my CD-ROM simply too old for this?

Any help would be greatly appreciated.
