On a -current from this morning, I can reliably trigger a panic by
"make release" (I believe the problem has existed for some time,
though).
The box can do make worlds without problem, but during make release,
it stumples at the same place every time.
This is a Dual P3 with all involved filesystems (/usr/src, /usr/obj
and the chrootdir) nullfs-mounted from a SU vinum raid01 volume.
monster# mount
/dev/da0s1a on / (ufs, local, noatime, soft-updates)
devfs on /dev (devfs, local)
/dev/da3s1e on /usr (ufs, local, noatime, soft-updates)
/dev/da0s1f on /var (ufs, local, noatime, soft-updates)
procfs on /proc (procfs, local)
/dev/vinum/vol/raid01 on /raid01 (ufs, NFS exported, local, noatime, soft-updates)
/raid01/usr/src on /usr/src (nullfs, local, noatime)
/raid01/usr/obj on /usr/obj (nullfs, local, noatime)
/raid01/usr/ports on /usr/ports (nullfs, local, noatime)

The panic:

I'll try to get a crashdump - 1GB (if anyone's interested?).
Config attached.
