Can you get the sources and compile your own FreeBSD? Your description
does not match my experience by any standards. The only problem that
often leads to crashes are lost devices. With other words, you mount a
device via USB and the connection gets lost (unplugged).

Try first the source. The best mailing list for this should be 'stable'
as it targets only the stable versions like yours.
