I think I've got all the right info, but here goes:

I'm trying to get my RICOH MP6200A CD-RW to work on
this new machine I just built.  I've gotten it to work
in the past, but it's always been blind luck.  This is
the first time I've gotten an oops however.

When I boot up, I get the following relevant messages:
.
.
.
Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes;
override with idebus=xx

ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
.
.
.
 I'm used to seeing the ATAPI cdrom or floppy? message
in the past... later in the boot process, the ide-scsi
module detects it properly.  here's where it kicks in:
.
.
.
scsi0 : SCSI host adapter emulation for IDE ATAPI
devices
ide1: unexpected interrupt, status=0x58, count=1
  Vendor: RICOH     Model: MP6200A           Rev: 2.20

lun 0
sr0: scsi-1 drive
..
.

The unexpected interrupt message is new.. I've never
seen that before.  When I login, i type 'eject sr0'
and i get the following:

  <0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing

Then it locks up hard.  After resetting, I get the
same messages as before, except for when the ide-scsi
module loads, which displays this:

scsi0 : SCSI host adapter emulation for IDE ATAPI
devices
ide-scsi: CoD != 0 in idescsi_pc_intr
ide1: unexpected interrupt, status=0x00, count=1

.
.

So now it doesn't know it's a RICOH anymore...
however, if i totally power down the machine, wait a
few minutes, and boot back up, it'll see it again.

Here's the output of ksymoops on the oops message:

ksymoops 2.4.4 on i686 2.4.18.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.18/ (default)
     -m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol
information.  I will
assume that the log matches the kernel and modules
that are running
right now and I'll use the default options above for
symbol resolution.
If the current kernel and/or modules do not match the
log, you can get
more accurate output by telling me the kernel version
and where to find
map, modules, ksyms etc.  ksymoops -h explains the
options.

I hope I've provided enough information.  I tried to
follow the oops-tracing.txt file, but couldn't follow
it well :/  If anything more is needed, let me know
and I will provide it.

Please CC me on responses as I don't subscribe to this
list anymore.

Toby
