Hmm. It breaks booting on my quad, I finally got around to testing without this patch and it turns out that it caused the boot failure I reported in another mail. This is with v2.6.23-6623-g55b70a0, a clean tree boots fine but with these two patches applied and configured in it fails during boot, hanging at some point, apparently when userspace is entered. On the other hand, it is fine with my original version. I'll have to find some time to check the differences hunk by hunk I guess. johannes
