ATAPICAM broken in 5.2.1 (did work in 5.2)?

Hi,

After upgrading from 5.2-RELEASE-p2 to 5.2.1-RELEASE,
with "option atapicam" I'm getting a panic on boot on a ThinkPad R32:

[...]
acd0: <UJDA730 DVD/CDRW/1.04> CDRW drive at ata1 as master
acd0: read 4134KB/s (4134KB/s) write 2755KB/s (2755KB/s), 2048KB buffer,
  PIO4
acd0: Reads: CDR, CDRW, CDDA stram, DVDROM, DVDR, DVDRAM, packet
acd0: Writes: CDR, CDRW, test write, burnproof
acd0: Audio: play, 256 volume levels
acd0: Mechanism: ejectable tray, unlocked
acd0: Medium: CD-R 120mm data disc


Fatal trap 12: page fault while in kernel mode
fault virtual address	= 0x300032c
fault code		= supervisor read, page not present
instruction pointer	= 0x8:0xc044bd00
stack pointer		= 0x10:0xc0c21bf4
frame pointer		= 0x10:0xc0c21bf4
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 0 (swapper)
trap number		= 12
panic: page fault
[...]
(messages typed)

There is no difference, if I disable ACPI or have a medium in the drive
or not. If I compile a kernel without "option atapicam" the panic goes
away.

Also, I'm getting strange error messages for the ATA slaves (there are
no slave drives attached at all) even without "option atapicam":

ata1-slave: FAILURE - ATAPI_IDENTIFY no interrupt
