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!
