Hi,
sorry, it's easilly reproducable.
I built a -current kernel supped today now without apm, acpi, usb.

- "boot -s" for singleuser
- "mount -oro /usr"
- "cd /usr/ports"
- "tar cf /dev/null . &"
- "tar cf - . | tar tvf -"
...wait...
...freeze...
...why?...

Could someone enlight me how to get some more usefull information after =
getting into ddb?
ddb(4) and the handbook is not really specific about.
Esp. how do I inspect specific processes which I see in "ps".
"trace" is of no help when manually breaking into ddb.
Is there something like "bt" or "up", like in gdb?

Bye/2
