Hi folks,

I'm currently trying both kernels (2.6.9- and 2.6.18-based).
With some tweaking they both compile cleanly, but on 2.6.18
the login shell crashes w/ segfault.

Its neither possible to attach via vzctl enter nor ssh'ing
is - the connection terminates immediately. Runing some
commands (also an shell) via vzctl exec works.

On 2.6.9 I don't have this problem.

Kernel bug ?

This is known problem, you've compiled OVZ kernel with CONFIG_PREEMPT.
The bug is already fixed, look at:

Ok, that fixed the problem.
I've added this to the wiki.

To me that makes little sense because we have already released a fixed
kernel (028test018).
