Can build 2.6.31.5 on one P4 but not another.

Can someone explain this to me.
I can build 2.6.31.5 on one of my Pentium 4's with no problems,
it boots and runs.

On a second P4, the build fails (compile works, load fails) with
comments about undefined references to:
sleep_on_common
and __up

These appear in
sched.c
and semaphore.c

I dont understand how this can build on one P4 and not another.

Same config files (I should have mentioned this)
Different gcc's
And I would assume that the loader is the only binutil involved

Are you using identical configs for both machines or not?

Are you sure both machines really have the same kernel source?

Have you tried if a 'make mrproper' makes a difference (normally it should
not)?

Do both machines have the same build environment (gcc version, binutils,
etc)?

If you need additional help, please post the exact error messages and the
kernel config for the failing machine.

Cheers,
FJP

P.S. Why are you building the kernels on two machines instead of doing the
builds on one machine and then copying and installing a build for the
second? That could save a lot of build time, even if you don't use
identical configs.
