>Release:        5.3 AMD64
>Organization:
n/a
>Environment:
AMD server with Tyan MB and dual CPU's.  I believe the system board is their Thunder MB.  eren at opensourcestorage.com can give full system specs (reference AMD system from Ray Johns)
>Description:
This has happened twice.  First time, I installed FreeBSD 5.3 AMD64 on the server (it's an eval server from eren at opensourcestorage.com).  Everything goes fine.  I log into the machine, make some changes to my shell/prompt, no problems.  I ftp an updated ports.tar.gz from ftp.freebsd.org to the machine, no problem.  As root, I cd /usr then issue rm -r ports/ so that I can remove the ports tree and untar the new ports and the system crashes/locks.  on the console, there are error messages.  I took a photo of them here:

I contacted opensourcestorage and they sent a replacement SCSI drive (it's a maxtore 18GB).  I installed the new drive, reloaded FreeBSD again and the system crashed again at the exact same spot when I issued rm -r ports
>How-To-Repeat:
install FreeBSD AMD64, delete ports directory
>Fix:
none at this time.
