You need to be more specific. What do you mean by "crash" -- do you get a system panic, a system hang, a reboot without a message? Is any output generated along the way? One common pitfall identified in the release notes was a change in default sizing of socket buffers, which requires some busy sites to increase nmbclusters (either by recompiling with different kernel configuration settings, or simply updating loader.conf to use a larger hard-coded value). Potentially, you could be running into that. If you're getting a panic, this can be debugged using the kernel debugging recommendations in the FreeBSD handbook. You'll either want to enable dumping of system core, or include options DDB in the kernel so you can debug live. You'll also want to build the kernel using debugging symbols so that the results are useful.
