:I'm getting the same problem as described in [1] with the most recent
:head revision. I just tried to "cvs checkout" and then the message
:appears repetitive and no further progress of cvs checkout seems to

That's a really old bug that was fixed a long time ago, or should have
    been.

I did recently (a few weeks ago) make some changes to try to prevent
    the buffer cache deadlock from occuring, perhaps I muffed it up.  I
    haven't touched that part of the codebase it in the last week, though.

Can you generate a kernel core (& binary) of the affected machine and
    upload it into ~/crash on your leaf account?  I'll take a look at it.

I got this today when trying to cvs update my pkgsrc tree. I'm
uploading a crashdump right now (*.14).

Were both of you guys doing major filesystem operations on the root
mount?

From looking at Peter's core the root mount point doesn't have a syncer
    vnode, and the new vnode recycling code won't run on it because of that.
    I am fixing it now.

What is interesting is that the vnode recycling code is not in error
    here, but instead has exposed a long standing issue in the code where
    the syncer was not running on the root filesystem every 30 seconds like
    it was supposed to.

Yes, I think both of us mentioned we were doing cvs checkouts/updates.
Additionally my mail server was processing a good amount of email.

Try it w/ that fix I committed.

Your commit fixes the problem. I close the bug report.
