Are those real crashes though?
For example, if you're using X, X sometimes wedges itself so it
doesn't respond to the keyboard.
[Aside: I'm still seeing instabilities in ncp support with 2.0.27, but
that's localized to specific processes now, and doesn't take down the
system as a whole. If I kill all such processes and terminate that
session with the novell server everything starts working normally
again.]
