Did you boot (Debian's) 6.17.2 kernel, copy its config from /proc/config.* to .config, then run "make localmodconfig"? If the problem is seen with it, we'd have to take a deeper look. Basically you can forget the bisection result. You felt into a local minimum during the bisection, and it doesn't point to the real issue. Takashi
