My Qube 2 seems to crash every week or so with no explanation, the system is currently sitting at the db prompt, the output of which commands would be useful to give an indication of what makes the machine fall over? trace output: cpu_Debugger+4 (ff00,f9,c6,2000) ra 800f13b4 sz 0 comintr+4d0 (ff00,f9,c6,2000) ra 802c9734 sz 64It looks your Qube2 got break signal (which activates ddb(4)) via its serial console. It could happen on some terminal which might pull its data line during reboot etc. In that case "continue" command may restart your Qube. You can avoid it by "sysctl -w ddb.fromconsole=0" (or put "ddb.fromconsole?=0" in /etc/sysctl.conf) etc.
hmm, that might have been me plugging in the serial lead, I've set "ddb.fromconsole?=0" in /etc/sysctl.conf as instructed & "ddb.onpanic?=1"
Will post back with another trace output if/when it hangs again? Thanks for your help Izumi :) Sevan
