Hi all,
As of the changes from Wednesday Sep 20, 2006, I see a panic in kernel
proper with the drbd driver loaded and io attempted.
I am investigating but I am hoping that some lights might go on and a
quick fix provided. Thanks. Below is the stack trace.

sorry, I did not notice this post...
just cleared your "moderated flag", though.
this got introduced by a broken "optimization" in r2433.
was fixed (I think) with r2451.
