Try making the mounts use acdirmax=0,acdirmin=0 (I'm not sure why that 
should help with the precise symptoms you mention, but I've known it to 
help with some NFS coherency issues in testing in the past).  (I'm 
assuming that the NFS file server is the system on which you're running 
"make check"; both systems using NFS from a third system may have other 
problems.)
