2.6.9-linode6 and FC2/CentOS3 login issue

If I wipe my linode clean, and do a default FC2 or CentOS 3 install, I can log in and out using lish with no problems. If I then move /lib/tls to /lib/tls-disabled and switch to the 2.6.9-linode6 kernel, I can log in and out once using lish, but once the login prompt reappears, I cannot get any keystrokes to appear. lish is still responsive: I can enter and exit the screen at will. But I can't log in to my linode using lish until I reboot, at which point I have exactly one login/out before it happens again.

Is anyone else seeing/can anyone reproduce this issue?

p.s. Sorry for reposting, but it was a tail on another thread, and not getting any answers.
