>Description:
I've just installed new server located at hoster's site and hardware.
I've used hoster's "rescue mode" running custom variant of 9.1-RELEASE/amd64.
I need "stock" 9.1-RELEASE, so I've downloaded FreeBSD-9.1-RELEASE-amd64-disc1.iso,
manually partitioned disks with "gpart" and made UFS2+SUJ file systems
using "newfs -U -j" command. Then I've extracted base and kernel there
and created fstab and rc.conf.
After reboot to newly installed system I've got:
# mount
/dev/ufs/root on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
/dev/ufs/usr on /usr (ufs, local, read-only)
/dev/ufs/var on /var (ufs, local, journaled soft-updates)
/dev/ufs/usrl on /usr/local (ufs, local, journaled soft-updates)
devfs on /var/named/dev (devfs, local, multilabel)
I ran "tar xf ports.txz" and "csup stable-supfile" in parallel, both working
with same file system /usr/local and got kernel panic soon.
After another reboot, I've got crashdump:
