Hi Michael,

It is weird that no other arch build show similar errors.
Building same linux-next on my machine seems to be fine as well.

>From looking at logs it looks like some sort of a make / paralle jobs timing issue
at build farm.

P.S. Could you also update system to also cc lkml and
linux-snps-arc at lists.infradead.org for such errors.

Thx,

That is weird. I'll ask it to rebuild it and see if it happens again.

Do you build with -j?

I'll add the arc list, I don't like to cc lkml so as not to annoy people with
too many error mails.

cheers

I did now - but still no error at my end.

OK.

It rebuilt OK the second time:

So there might be a gremlin in the Makefiles somewhere.

I always build our kernels with -j4 or even -j8 depending on the machine I use
and I've never seen issues with parallel building.

Latest I tried was 4.4-rc4.

I just saw the same failure on another arch, so it doesn't look like its
anything to do with arc.
