FYI: This is without the skas patch, with a stock RH9 kernel on the host.

Any thoughts or coroboration would be appreciated. Clearly this is a
bug in the RH9 kernel. 

I'm not sure the revision.

I've made some progress with make check on Red Hat Linux 9, but I'm at
a problem that looks bad.

I have some UML kernel processes appear to be unkillable.  They don't
respond to kill -9 by me, nor to kill -9 by the superuser.  They are
not zombies.

Here's one that I"ve attacked:

F   UID   PID  PPID PRI  NI   VSZ  RSS WCHAN  STAT TTY        TIME COMMAND
1   104  7622     1  15   0 33404 7200 get_si T    ?          0:00 /home/hugh/swan/umls/uml2.4.22-sept/umlbuild/east/linux (east) [lwdnsq]                                                                                        !

As far as I know, that means we have a RHL9 kernel bug.  No process
should be unkillable.

Second opinion, anyone?
