Hello,
I am able to make my Sharks wedge nearly at will.
* start PVM on 8 of them.
* start xmandel (an pvm application, that will distribute work to all
configured PVM nodes)
* wait...
repeat until one of the Sharks wedges.
Definition of "wedge":
- doesn't react to serial console any more, not even to a break.
- doesn't react to network, especially: doesn't pong when you ping it.
- the front LED is either steady green or steady off.
- the inside yellow LEDs are steady on.
- the inside green LED is happily blinking, as if it was connected to
network activity (is it?)
Machine configuration:
- diskless
- 64 MB of RAM.
- 47 MB of NFS swap (apparently, not used at all)
- /dev on mfs
- /tmp on mfs (but not used very much)
The 8 sharks are connected to a desktop Ethernet hub, which in turn is
connected to a catalyst switch which connects to the server.
The kernel can be netbsd-1.4: shark-netboot, or the same built with the
fixed bcopyinout.S.
Any idea what to do to debug this?
Regards,
Ignatios Souvatzis
