I tried simplified versions of the bug trigger on two machines
running 2.6.32-rc1-git6, and neither triggered the kernel bug.

The original recipe involved doing a glibc rebuild, run its test
suite, install it, and reboot. Today however machine 1 was already
doing a rebuild so after the rebuild it did a reboot into the new
kernel before the install. The second machine booted the new kernel
directly to install the binary packages from the first machine.

I'll re-run the full bug trigger recipe on a third machine later next
week (it must rebuild glibc itself anyway due to arch differences).
