It is reproductible (just reboot). Doesn't happen on vanilla 2.6.18. (It is to be noted that this box is having some trouble with recent versions of the kernel, that may or may not be related to this Oops, see the thread ".BUG-lockdep and freeze (was: Arrr! Linux 2.6.18)". However the symptoms are different, so maybe this is of interest.) I can git-bisect it if you think it could be useful. er. P.S.
