SubjectRe: Simple script that locks up my box with recent kernels

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.

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..
