Hi Zlatko,

I am not sure if I hit the same problem as described in this thread.

Under heavy load, while building a customized toolchain for the Freetz
router project I got a BUG || NULL pointer derefence || kswapd ||
zone_balanced || pgdat_balanced() etc. (details see my screenshot).

I will try your patch from [1] ***only*** on top of my last
Linux-v3.8-rc1 GIT setup (post-v3.8-rc1 mainline + some net-fixes).

Yes, that's the same bug. It should be fixed with my latest patch, so I'd
appreciate you testing it, to be on the safe side this time. There should be
no difference if you apply it to anything newer than 3.8-rc1, so go for it.
Thanks!

Not sure how I can really reproduce this bug as one build worked fine
within my last v3.8-rc1 kernel.
I increased the parallel-make-jobs-number from "4" to "8" to stress a
bit harder.
Just building right now... and will report.

If you have any test-case (script or whatever), please let me/us know.

Thanks.
