Hi Andrew,

Not able to boot 2.6.25-rc3-mm1 my ppc64 box.
2.6.25-rc2-mm1 and 2.6.25-rc3 boots fine.

I applied slab.c fix also.

Any other known issues ? My config file attached.
Here are the messages on the console.

Thanks,
Badari

The semaphore consolidation code enables interrupts early in boot, when it
shouldn't.  This tends to make powerpc blow up.  Could be that this is what
you're hitting.

Matthew, is this ging to be fixed soon?

Thanks.

Yes. I just backed out git-semaphore.patch and machine booted fine.

There is a new version of these patches in the current linux-next tree ...
