FreeBSD roxy.zellis.com 7.2-RELEASE-p2 FreeBSD 7.2-RELEASE-p2 #0: Wed Jun 24 00:57:44 UTC 2009 root@i386-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC i386
>Description:
On Sept 5, 2009, I performed fresh install of 7.2 on new boot disk. Have since experienced 4 kernel panics. Common element in stack trace is pmap_remove_all(), but that could be a coincidence, I guess.
Machine was very stable with FreeBSD 5.x before loading 7.2.
vmcore.0 and vmcore.1 are from trying to start X.
vmcore.2 and vmcore.3 are from running a java application.
First three cores are from the generic -RELEASE kernel. The last core is the generic -p2 kernel.
