OK, I see what you mean.  Your Venus on PPC works for a number of
commands (what are they ?) but not the command "ls /coda", right ?

In this case, this may need a bit of debugging.  You may be interested
in writing a tiny program using the syscalls "getdents" (which is what
"ls" uses) so as to narrow down the problem a bit.

About the kernel message you posted:

I think the message about "downcall, no SB!" can be safely ignored
(it used to be the case that Venus tried to write to /dev/cfs0 once
too early upon venus startup, but that bug is not critical).  I don't
exactly understand the rest, I guess Peter knows better.

Good luck !
