 Also a common panic at my setup (Intel Q9450) when surfing with firefox. 
 Maybe triggered by npviewer.

 Module Name:	src
 Committed By:	skrll
 Date:		Fri Sep  5 14:01:11 UTC 2008

 Modified Files:
 	src/sys/miscfs/procfs: procfs_subr.c procfs_vnops.c

 Log Message:
 PR/39324 kernel diagnostic assertion "l->l_stat != LSZOMB" failed.

 Ignore procs with zero or all LSZOMB LWPs. Get a non-LSZOMB LWP to perform
 operations against as part of the deal.

 procfs really needs to be updated to support multi-threading fully.
