I just got this panic on a -current kernel from March 17th, running
on a 486/66DX2 with 16 MB of RAM:

At the time, the machine was simultaneously doing a "cvs update" of
/usr/src from an NFS-mounted repository, and an "rm -rf" of a large
directory tree on the local disk. I've been running the kernel since
March 17th, and this is its first panic.
I'll save the kernel and the crash dump in case more information is
needed.
