freebsd stable - Apr 2005 - Preposterous errno values from kernel

I'm getting this on a RELENG_5_4 sparc64 system (e4500):

# rm -rf *
/bin/rm: Unknown error: 7283.
# ktrace rm -rf *
/usr/bin/ktrace: Address already in use.
# ktrace /bin/rm -rf *
/usr/bin/ktrace: Software caused connection abort.
# ktrace -di sh
# /bin/rm -f *
/bin/rm: Network dropped connection on reset

[...]
   505 sh       CALL  execve(0x22c0c0,0x278010,0x277e10)
   505 sh       NAMI  "/bin/rm"
   505 sh       RET   execve -1 errno 52 Network dropped connection on reset
   505 sh       CALL  write(0x2,0x22a080,0x2d)
 
# ktrace -di sh
# rm -rf *
rm: Unknown error: 7283

[...]
   510 sh       CALL  execve(0x277ee0,0x278010,0x277e10)
   510 sh       NAMI  "/bin/rm"
   510 sh       RET   execve -1 errno 7283 Unknown error: 7283
   510 sh       CALL  execve(0x277ee0,0x278010,0x277e10)

I have verified that the kernel is up-to-date and there are no
extraneous patches in my source tree.  It has survived a kernel clean
and rebuild.

Cute.  Does it affect anything other than /bin/rm?  Is /bin/rm sane
(not some random junk that's confusing the ELF loader)?  Is this an
SMP system (which might point to locking problems)?

If this seems consistent (other than the actual errno reported), the
quickest solution would seem to be to use DDB (or kernel GDB) to
follow the execution path from execve() until it goes off the rails.
