RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 07) BWT, my latest ubuntu 12.04 box is often freeze.(mouse stop, any keys: Ctrl+Alt+F1/Del, NumLock, CapsLock etc are not reponsible) I tried check hardware: run "sensors" command , and CPU temperature is ok(~30C) (most time, the freeze occured when CPU load is not high) check memory, passed. run disk check, passed and run some games, e.g: torcs, Never freeze. It seems that the freeze mostly occurs when opening/saving files. but I can not reproduce it.
