kernel: nfs4_map_errors could not handle NFSv4 error X

[Mark Heslep]

Im picking up bursts of  nfs4 kernel errors on the client end of stock 
FC2 smp kernel 358, nfs-utils-1.0.6-22:

nfs4_map_errors could not handle NFSv4 error 10008
and many more 10025 and a couple 10026 errors

client mount options:
type nfs4 (rw,rsize=8192,wsize=8192,intr,addr=xxx.xxx.xxx.xxx)

server exports options:
xxx.xx.x.x/24(rw,fsid=0,no_root_squash,insecure,no_subtree_check,sync,anonuid=65534,anongid=65534)

The NFS server is running the latest FC3 ish development kernel 
2.6.8-1.541. (and also utils 1.0.6-22.) 

Traffic is moving ~ okay but I needed a newer kernel on the server as 
NFS traffic slows and eventually freezes up between two 358 kernels.  
The newer kernel on the server seems to keep the traffic moving though 
as reported above the FC2 client box is spewing these occasional 
errors.  Any comments before I bugzilla?  Google gets amost zip on the 
logged error.
