A deterministic (SMP-)oops in nfs_file_close was fixed in the
2.1.117-ac* series.
There is also a hard lockup. The probability of this lockup was lowered
by
the fix that removed the nfs_file_close oops. It was always possible to
trigger
the lockup by pounding enough on the NFS-client subsystem.

Stats for the netscape-folder-test:

2.1.117ac1 passes 2 out of 2 (but later crashes on a large cp -a)
2.1.118 crashes 2 out of 2

This crash has never occured under UP.
