ips(4) in toaster mode

After upgrading RELENG_6 from Jul 11 to Sep 30 on an i386 box,
everytime I run tar to backup my system to a mounted nfs volume.
After one hour of operation, it panics with sleeping thread. Upgrading
to RELENG_6_2 does not help. Also, the console is complete
hang, I can not break into DDB at all. The only thing is do power

Also, the only harddisk on that host is the ips(4), so I can not obtain
a kernel dump. I'm not sure if this is a hardware failure, at least, no
led on the panel is shown red...

OK, the only information on console is attached below. Any suggesstion
are welcome.
