[uml-devel] Stranded processes on halt with 2.6.9 host (2.4.26 client)

[uml-devel] Stranded processes on halt with 2.6.9 host (2.4.26 client)

[Doug Dumitru]

I have been running 2.6.7 on the host for some time in SKAs mode.  When 
trying to upgrade to 2.6.9, 2.4.26 clients do run correctly, but upon 
shutdown they leave two processes stranded that cannot be killed (even 
with kill -9).  Both processes show [halt] so this must be very near the 
end of UML shutdown.  Any ideas.  I hunted the message list, but did not 
see anything obvious.

Server is a Dual P-III running fresh Fedora Core 3.  Kernel.org 2.6.9 
kernel has been tried with:

     15957 host-skas3-2.6.7-v1.patch
     23838 host-skas3-2.6.9-rc4-v6.patch
     25510 host-skas3-2.6.9-v7.patch

but they all behave the same way.

It's on *any* 2.6.9 host (search "zombie" on the list and you'll find many 
info). Some UML kernels have been partially patched for that... but some 
problems are only due to the host kernel and not workaroundable.

This particular one would crash IIRC (even Oops the kernel).... at least on 
2.6.9 prereleases.
