How come the number is so important for you?  What do you think if you
have to drop into single user mode and adjust fstab manually and the box
is several thousands of miles away from you after a simple 'make
kernel'?  I think changing this behavior is a big POLA and not the right
thing to do.

Please provide links on the wiki if you really want it to be useful.

I think the only ich9 issue I am aware of so far is that a specific
model of it is not recognized.  This is fixed in HEAD and RELENG_7.

Is the problem still exist for latest RELENG_7 and RELENG_6?  Who can
provide some basic testing for a new snapshot?

No, it does not help if that's just "it panics", "foo is not supported"
if no detailed information is provided and we don't have our hands on
the actual hardware.

Again, it does not make sense if we don't even know how to contact these

Could you please provide some more detailed information (e.g. previous
posted message-id or a link to mail archive)?
