The only extra patches to 2.4.19 are the NFS patches, so
I don't believe so unless it was included in 2.4.19.

We are using config_himem, because at least some of the
machines we have will have a bit too much memory.

I will try turning that off and see if it makes a difference, is
this on the client or the server or both?   I am pretty sure
we have it enabled on all of the nfsall patched 2.4.19 builts.
