Hi Dave,

The only bug report I remember getting from you had no details and was
in reply to another bug report which was, indeed, addressed, so we had
every reason to believe it was being dealt with with the patchset which
did indeed go into -rc3 (and does address a problem with initramfs in
particular cases.)

Clearly James Morris' problem is something unrelated, and regardless of
course of action we need to track it down.

If you also are having problems with -rc3 we would really appreciate as
much detail as possible -- boot logs at the very minimum -- so we have
a chance to at all track down the problems that do exist.
