I recently encountered strange problem. When system is left idle, (well, compilation stops for some reason, no compilation is done, the same when it performed some simple router functions) for a couple of hourd when I approach console and try to ececute any command I get messages saying that there's no such command, sometimes emerge tells about bus error and HDD LED is constantly on. The system works but I cannot execute any command, not even halt or reboot. It bothers me because I would like to switch mostly to linux when I buy new sound card in a couple of weeks. Could It be a problem with SARA support? Msybe someone encountered the same or similar problem or heard about it somewhere.
