a reliability problem with it. Used it during 2.3 without problems. Have
used it twice now in 2.5 Alpha and that worked, too. Sure, I've found some
bugs. That's what Alpha and Beta testing are for. But I never ran into
data corruption or anything else that would lead me not to trust upgrade.
I don't have a particularly simple configuration, either: I have two
upgradeable disks, two (different) frame buffers, and a custom set of
packages. Not only that, I generally take advantage of the fact that the
system is alive and on the network during Solaris upgrades, and do some
random stuff (like playing games :-) while the upgrade is taking place.
Nothing is perfect. If you can provide more information on your exact
configuration and a stack trace from the core dump, perhaps we can help
you figure out what's going wrong. I've found the install team to be
very interested in finding and fixing bugs.
