That's the last thing in the world my patch should cause to happen. rc4 to rc5 also contained no changes that should have made that problem go away, so something else is afoot. I have X fully working on my ultra5 with a one-line patch to Ubuntu-feisty's xserver source tree which should be entirely irrelevant to your cases. I've tried everything to reproduce that test program failure on any of my systems and I can't, so could you do some detective work to try and see if maybe it's PREEMPT or a miscompile or something like that? I'm out of ideas, so your help in doing the debugging to figure out where this comes from since I can't make it happen here is appreciated :-) - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
