My system keeps hanging every several hours. I think the problem is somehow connected with network, because plugging ethernet cable eliminates the problem (even if ethernet is used locally only). If I try to use WiFi without ethernet plugged - system hangs in couple of hours.
- I see no common pattern in kernel logs after it. If I am getting the idea right - it means that system can't write to HDD at that moment?
- I can't use netconsole, because my wifi doesn't support spooling and with ethernet plugged problem doesn't show itself.
If I leave terminal opened - it fades to black after error so gives no information.
How can I diagnose and eleminate the problem in such situation?
