I just got the following panic while running a multitude of doscmd
sessions compiling with MSC 5.1 (possibly non-related):

Jan 27 00:14:45 shad savecore: reboot after panic: nfs: sillyrename dir

This was on an NFSv3 hardmounted filesystem. Is this problem known and
being worked on? (my last reported problem apparently is)

I didn't get a core, because my root partition didn't have enough
space.
