NFS Problems with kernel 2.2.1 (and 2.2.0, but not 2.1.x or 2.0.x)

["Adam Alexander" <adam tjconline com>]

After upgrading to the linux kernel version 2.2.0 monday evening, I started
to recieve the following messages on startup when my scripts started to
mount two nfs exports from another redhat 5.2 machine (which is running
kernel 2.0.36).

One weird thing is that the NFS shares ARE mounted and DO work.  There is a
less serious sounding error upon unmounting them, and then when remounting
them the same messages as above appear.  These messages have only happened
under 2.2.x (I have tried both 2.2.0 and 2.2.1 now).  When I revert back to
my 2.0.36 or 2.1.(something fairly recent) kernel the problem goes away.  I
am using a redhat 5.2 machine with all errata applied.  If anyone has any
ideas please let me know.  =)

Thanks,
