I'm using the latest linux git pull. One trivial thing to try would be to just bisect it. I assume 2.6.26 is fine, so while it will take a few boots to try it out (there's 8111 commits in between, so 13 reboots should do it), the advantage of bisection is that it's fairly straightforward to do even if you don't have any clue where the problem might lurk. And with your machine, recompiling the kernel 13 times shouldn't take that long ;) Linus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
