Hello again

OK, I got things to compile [I hadn't done enough "make clean"'s it would
seem]

after copying the created vmlinux file to / on the machine [it is running
Irix 6.5] I then rebooted into the BootProm and told it to
"boot vmlinux"

It then gave this:

[------------------------------------]

PANIC: Unexpected exception

Typed that in by hand, hope there are no mistakes

if I look up the PC in the System.map file I find

0000000088147eec T sgi_sysinit

and if I do an objdump I find:

0000000088147eec <sgi_sysinit>:

    .....
    continues for a while

any hints what might be wrong?  I can send a .config to anyone who might
want it.

The cross compiler tools are from the i386/mips-linux .rpm file on
oss.sgi.com....
