Yep, one of the machines is running an NFS server.  Unfortunately,
it's necessary at the moment.  The other machine isn't, but also had a
different kernel error:

IPUT Bad refCount 0 on inode 0xd0a1e000

If either is compiled, it's been compiled from the RedHat source RPMs.

Where can I find this version?  I don't see it available on the
