Ok. It does smell like you marked somethign good that wasn't. That commit 1db27c11 was the last one you claimed was bad, of course, so it's the one git will claim caused it, when you've marked its parent good. > Where do I go from here?

Yeah, trying to do sysrq when it locks is probably worth it. As is enabling debugging things (netconsole, page-alloc, slab alloc, lockdep etc). But if nothing seems to really give any clues, you might just try to restart bisection with git bisect reset git bisect start git bisect good v2.6.17 git bisect bad 1db27c11 and just run the resulting kernel version for a day or two. If an hour wasn't really good enough, it's not as repeatable as we'd have wished, but even if it takes a few days to narrow it down by just two bisections or so, it will cut things down from ten thousand commits to "just" 2500..
