Subject: SCSI emulation causes kernel panic

Greetings. I haven't been able to find a single version yet in
the 2.5.x series that allows me to use SCSI emulation without a
kernel panic...until I tried a strange trick today. Even under
2.5.63, I still received the panic documented below, until I
turned on all the options under "Kernel Hacking". Then SCSI
emulation seems to work fine!

Some details: I have a dual Athlon MP2000 on an ASUS A7M266-D,
with a new IDE-ATAPI Plexwriter. I have attached the dmesg/klogd
output, the kernel panic that I painstakingly transcribed by
hand, and the kernel configuration I used. If there is anything
else needed...let me know!

That might actually be useful info. What affect does the slab
poisoning option have in paticular.

Note to self: even though the panic disappears, and the device
appears in /dev, when the device is actually _written_ to using
cdrecord, various scsi errors happen. Blurf.

Need to run that oops report thru ksymoops (see the file
linux/Documentation/oops-tracing.txt) or turn on
CONFIG_KALLSYMS=y in the Kernel Hacking menu to decode all of those
hex addresses.
