 I've been experiencing this bug as well.  In my case, like bug 43287,
 it appears to be happening after the nightly cron jobs.
 
 I'm running the generic 6.0_BETA2 release kernel in VMware ESXi 5.0.
 With the exception of the system disk most of the storage in this
 system is being provided as Raw Disk Mappings of iSCSI luns from esx
 and is being managed with NetBSD's lvm.  The volumes are all formatted
 with FFSv2 and mounted with the log option.
 
 The latest core dump and dmesg output can be found below:
 ftp://ftp.muleslow.net/netbsd/cores/dmesg.out
 ftp://ftp.muleslow.net/netbsd/cores/netbsd.6.core.gz
 
 The relevant excerpts from dmesg:
 
 panic: kernel diagnostic assertion "oldsize != VSIZENOTSET || pgend >
 oldsize" failed: file "/usr/src/sys/uvm/uvm_vnode.c", line 350
