You copied the list by hand, didn't you ?
Are you sure there were not revision after the symbol names,
such as "printk_R1b7d4074" ?

There should be and 'R' followed by 8 hex digits here. I remember I
already came across this once, but unfortunately I don't remember how
nor how I fixed it.
When I build from your .config, I have "printk_R1b7d4074" for example.
It is defined in include/linux/modules/printk.ver which is dynamically
generated during make dep :
#define __ver_printk 1b7d4074
#define printk _set_ver(printk)
#define __ver_acquire_console_sem f174ed48
#define acquire_console_sem _set_ver(acquire_console_sem)
#define __ver_console_print b714a981
#define console_print _set_ver(console_print)
#define __ver_console_unblank b857dfed
#define console_unblank _set_ver(console_unblank)
#define __ver_register_console 80c5241f
#define register_console _set_ver(register_console)
#define __ver_unregister_console d83dc0dd
#define unregister_console _set_ver(unregister_console)
So I suspect that this file was not included at all during build. Stupid
question : are you really sure that the bzImage you boot from has been
rebuilt and that you're not running an old one ? Have you performed a
"make distclean" before you have built the kernel for the first time
(save your .config before doing this).
Hmmm while I'm thinking about it, please also ensure that you have
'genksyms' somewhere in your path.

Should be OK.

I'm sure it will work.

I understand, what I meant is that 8390 relies on crc32.o which might
or might not be included in the kernel. I wanted to identify the
possibility that some modules might have been missing.
