If yes, did you used it before the breakpoint trap was reported ? to be honest, I do not know if ddb is compiled in. The main problem would be that this is currently only machine. It also has no serial links. Just USB and Ethernet. Did you used gdb or strace in the usermode before the trap ? No debugger of any kind was running. Let me tell you what I normally do when I start this machine. It has an Intel i7 CPU and as such it uses KMS. - log-on as a normal user. - start X - start a few xterms - start wireless network in one of them - start chrome to log-on onto the LAN of the client - start claws mail - start arora I think that I did not come further as I remember to get a message from my daughter as the last activity of the machine in chrome. The screen went black then and the machine started to reboot. I think that there is not much helpful information I could give. I work since then much longer without any problems.
