I remember coming across the same error during buildkernel last week, but
can't remember how, or how I resolved it. I've just built GENERIC from recent
sources and can get the assert to occur by running "config -x
/boot/kernel/kernel". It looks like it thinks there's more data available
than there is.
config/main.c gets the size of the configuration by running elfdump:
> elfdump -c /boot/kernel/kernel | grep -A 5 kern_conf | tail -2 | cut -d ' '
-f 2 | paste - - -
10053368 2656
The first column is the offset, and the second is the number of bytes, but the
embedded configuration only has 2649 bytes.
Some of the output from config:
> config -x /boot/kernel/kernel
options CONFIG_AUTOGENERATED
ident GENERIC
machine sparc64
cpu SUN4U
