*shrug*  That's why I asked.

The reason I hesitated is I use miniconfig files rather than big .config 
files, and some people get confused by that.  Drop the attached 
miniconfig-linux in the kernel source directory and go:
  make ARCH=sparc allnoconfig KCONFIG_ALLCONFIG=miniconfig-linux

That expands it to a big .config file, and from there "make ARCH=sparc 
CROSS_COMPILE=sparc-" to reproduce the problem.  Assuming you have a sparc 
cross-compiler lying around.

Disable CONFIG_SCSI_SUNESP and it builds to the end, (and the result boots but 
won't mount the root filesystem, which is sort of expected).
