Just wondering if anyone has tested ext4 on s390. I see that some
assembly bitops got fixed upstream, but even with those in place I'm
hanging when ext4 tries to init bg's:

I'm now struggling to get an s390 booted on an upstream kernel to test
that, but I know about -><- about s390s.

I managed to boot 2.6.26.2 (stock) on an s390; same problem. :(
IBM, help? :)
