Hi !
I need some advice regarding a full reinstall for an 2xP133 server (Tyan
Tomcat III S1563D with AHA2940AU).
Currently I have 3.0-9702090-SNAP with the pre-Lite2 kernel (and its
aic7xxx SCSI problem); I plan to install a newer 3.0-current version and I
have to choose between the 3.0-970618-SNAP on the official FreeBSD server
and the daily snapshots from current.FreeBSD.org.
The problem is that this is a production server (which sustains all our
ISP services) so I need it to be as much stable as it's possible. What are
your opinions ?
From what I read on the -current and -smp lists I understood that there
are some minor problems with the 06/18 snapshot and also that Steve is
started the long awaited move from the 'giant lock' to the 'finer grained
lock' kernel architecture, which means current kernels are pretty
untrustable.
For the situation to be clear I attached an 'mptable -verbose -dmesg'
output.
All your comments are welcomed and appreciated.
Thank you very much; apologises for any trouble caused.
