Another data point - I'm running 9.2, svn to 9-stable, and my ports
tree is kept current with portsnap.

On Wednesday (25 Dec) I built the "devel/arduino" port, which pulls in
openjdk-6.2.  I was using a /usr/src & /usr/ports updated 13 December.
The kernel was r259382:.  Everything worked great.

Thursday, I did

 	      svn update /usr/src
 	      portsnap fetch update

(the svn is against 9-stable), rebuilt world+kernel, and ran
'portupgrade -a'.  That gave a r259923 kernel.

Arduino now reliably takes the box down, no dump, just a freeze /
reboot.  Rebooting on the older kernel doesn't fix anything.
