Hi Julian,
One problem is that the floppy disk must NOT be built as a module on
sparc32. Either remove floppy support or build it into the kernel.
CONFIG_BLK_DEV_FD=m will fail.
The other problem can easilly be dealt with by not building the
CONFIG_PARPORT_AX88796 module. If you rearly need this module then some
debugging will be needed to work out what has been broaken.
Sparc32 apears to have a 4M limit in memory space for the boot
loader+kernel. For me (with SunOS 4.x boot loader) this equates to a
maximum kernel size of app 2.9MB. I understand that for SILO it is
arround 2.7MB.
Cut out any unnessesary debugging capabilities in the kernel
(eg. things like CONFIG_SLUB_DEBUG, CONFIG_DEBUG_BUGVERBOSE).
Do not build any un-nessesary modules (if you remove too many of them,
you can always rebuild with the missing ones later on when you know you
can get create a working kernel).
There is an important bug fix for sparc32 (arch/sparc/lib/memset.S). Check
that this has been applied (my mail client will nodought mangle it):

This makes no sense as these functions are definitely compiled into the kernel.
I will provide more detailed error messages later as this system is
currently attempting another kernel compilation.
Ok, the compile failed, and the errors are:
Building modules, stage 2.
MODPOST 165 modules
ERROR: "ioremap" [drivers/parport/parport_ax88796.ko] undefined!
ERROR: "iounmap" [drivers/parport/parport_ax88796.ko] undefined!
ERROR: "floppy_hardint" [drivers/block/floppy.ko] undefined!
My .config is attached.
I know that I am able to eliminate the driver causing the first two
warnings from my config as I don't have a parport of this type,
however I feel that the errors it causes are a concern.
The floppy driver I'd rather like to have compiled though. =)
Again,
Thanks in advance,
