Hi Kurt,
This time it worked after I placed the module sources under the drivers/scsi
directory. The module loaded on SMP kernel without giving
unresolved-symbols
errors. I guess, the key is to use the right CFLAGS while compiling the
module. You were right. I was using my own makefile. After I modified
the makefile, everything went smoothly.
Thanks a lot for the help.
