Indeed -- it's a fairly esoteric test case. It was part of a tarball of similar tests posted by either Bodo Stroesser or Jeff Dike to linux-arch, probably some time in or around 2003, when UML tripped over the bug. I fixed it on PPC and PPC64, and I thought it got fixed on other architectures at the same time. I'd be more specific about the archive reference, but unfortunately the PC with my archives on it is refusing to boot at the moment so I can't be more helpful until I get home from LCA. But when I wanted this, I was able to find it by grepping my archives starting from little more -- it shouldn't be hard to find. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
