Hi Alessio,
I have precisly what you describe
here.
I'm using Fedora Core 4 with SKAS3 on both a twin
686 Dell and also in x86_64 mode on an IBM x336.
The UML kernel is 2.6.12 patched with
bs7.
When running in tt mode both systems hang at
init.
Like you I also can run /bin/sh, /bin/bash, and
even init="/bin/ls -lsa" and it all works, *until* it needs to start another
process.
I have FC4 running in SKAS mode on the dell twin in
32 bit mode. However, SKAS3 is not up and running yet (from what I
understand) on x86_64 hosts, so I only have TT mode available to me for that
machine architecture (eventhough SKAS3 compiled in ok and is
detected).
From what you've done and what I've done (which I
posted on the user-list) it seems your conclusions are pretty close to the mark
from my reading.
Everything you describe is happening to
me.
Sorry this doesn't help. I think right now your
only option is to go SKAS3 on a 32 bit host, and SMP works ok. It's
also beyond my understanding to into the guts of the kernel and figure it
out.
Cheers
Phill.
