I posted the following message to linux-kernel on the 12th. It has not
had any response and I have more information that may be of help to an
extra focussed group like linux-scsi.
I was previously using kernel 2.1.132 with the SONY 926S CDR using the
AHA1505 controller. This combination was working great. Recently I got
the MATSHITA CW7502 CDR and I'm using it on the same controller (and I
moved the SONY burner to another machine).
I don't use CDs often either, so it wasn't until 2.2.3-ac1 that I just
noticed that trying to copy a CD (using dd if=/dev/scd0 of=iso) caused
a kernel panic, as in the information attached below. I have done more
tests and verified the same fault with 2.2.3-ac4 and 2.1.132.
The SONY 926S is a 2x/6x burner, whereas the CW7502 is a 4x/8x. Is the
new drive simply too fast for the controller? I believe the 1505 has a
maximum limit of 3Mb/s, which should be more than enough. Is there any
known problem with this CDR unit, or is the controller incompatible?
Please note that it seems that others have noted the same problem. Bug
report #33800 on the Debian Bug Tracker appears to be the same problem
though the recommended fix was to comment out the panic call :-/
The following information (just repeated from the original report sent
to linux-kernel) contains lspci, the kernel panic, and the information
provided when inserting the module. Any other info required?

Subject: Kernel Panic reading scsi-cdrom
I'm having trouble with a scsi cd-rom on linux 2.2.3-ac1. I'll be trying
linux 2.2.3 without the -ac1 patch later tonight to confirm the official
kernel is at fault. The problem is known to also occur with 2.2.2-ac7: I
can't precisely pinpoint which kernel started causing troubles though (a
lot of hardware has moved into/outof this box recently).
The problem manifests itself as a kernel panic when running
dd if=/dev/scd0 of=raw.iso
The kernel panic occurs quickly; within the first few megabytes.
The system requires a reset, though sysreq allows me to unmount and sync
the disks first. The kernel panic log is written below. It was copied by
hand onto paper, so I can't guarantee perfection, though some effort was
made to avoid errors. Information from the aha152x modprobe and lspci is
also given. The kernel was compiled with gcc-2.7.2.3.
I've repeated the error twice. The second produced an exact match of the
kernel panic *except* the number 0xc0fdde00 became 0xc031be00. My system
map doesn't have any symbols with addresses this high (my kernel symbols
are all prefixed by 0xc01). The fault occurs with and without X, and I'm
not using a soundcard or tuner card at the same time.
The scsi adapter is an ISA based Adaptec 1505, so there is no BIOS. I've
checked interrupts and IO ports and I can't see a conflict.
The same hardware works fine under Windows 95 (temporarily installed for
the purposes of proving the hardware wasn't broken or misconfigured).
