** Description changed: Since upgrading from 10.04 to 12.04, my server suffers from frequent freezes. I have been unable to find a pattern and the freeze 'behaviour' is not always the same: usually the system does not respond at all anymore, and sometimes an error message is printed to the console: BUG: unable to handle kernel NULL pointer dereference at (null) free_thread_info+0xb/0x30 The attached kern.log file has the full error messages. Usually the system can reboot using Alt+SysReq+B, but sometimes that doesn't even work. And on rare occasions the keyboard lights start blinking. Now, there might be more than 1 problem at hand here, but at least I've got an error message now. - PS: on 10.04 I also had occasional freezes, but that averaged once every - 3 months or so. Now it happens once every three days. + PS: on 10.04 I also had occasional freezes, but that averaged once every 3 months or so.
