[Openchrome-users] CN700 problems.

[Christiaan van Dijk]

Just checked it with a remote VNC session. After the crash I can access 
the system and reboot, log files provide no info. Problem did become 
worse during all the experimenting, not sure why. Starting point was 
identical to what you described, system runs but crashes at the 
combination of heavy I/O and other random screen related actions. Will 
try to get back to this starting point and see if the system can still 
be reached through VNC when crashed.

Anyway, is there a way to extend the information logged by the display 
driver? Think there should be but I don't know how.

Regds,
Christiaan.
