OK, good.

I'm sorry but I don't have any idea where the problem is. So far as I
can see, there are no bug fixes to drbd or ocfs2 in 2.6.36-rc5 that are
not also in 2.6.35.6. Maybe the bug is elsewhere and just triggered by
this combination of storage driver and filesystem. Or, given that you
said that even 2.6.36-rc5 did crash once, it could be that the hardware
is unreliable.
So there are two things you could try, but I am not very hopeful:
1. Run a RAM test such as memtest86+.
2. Use 'git bisect' to find the change that makes the difference.
Normally you would use this to find when a bug was introduced, but
you can also use it to find when a bug was fixed if you reverse the
'good' and 'bad' labels.
See <http://book.git-scm.com/5_finding_issues_-_git_bisect.html>.
